The Subtle Beauties of Colorful Christmas Lights–reflections, refractions, and shadows.

Reflections, refractions, shadows, and colored lights.

The winter solstice has come and gone, and the daylight is getting longer. We’ve enjoyed the light of candles, holiday decorations, and (sometimes) fireworks. So today’s post is just a look back at some of the interesting and beautiful effects that light can have.

Let’s start with some reflected lights–but colored lights.

Not only are colored lights beautiful, but their reflections are also beautiful and interesting. And then there are the interesting shadows they cast along with the reflections.

I like the light-and-shadow effects almost as much as I like the tree itself. Almost.

When I was young, “holographic” paper and foil was a very fancy and expensive item. I think I paid a dollar apiece for some postcards with a holographic coating as a teenager–I’m not sure what that equals in today’s dollars. Today you can buy wrapping paper that is thin plastic with all sorts of nifty holographic effects, wrap gifts in it, and then throw it away. It’s that cheap.

I don’t tend to buy the holographic wrap because it doesn’t fold neatly and doesn’t tape as well as paper, but I do appreciate all the fabulous light effects available with holographic film. I have several electric candles filled with liquid and holographic glitter, and I find them mesmerizing. They also refract and reflect light in interesting ways.

I deliberately cropped photos to emphasize the interesting light effects, but in case you want to see where they came from, here are some of the original photos.

I also have some previous posts on light effects.

Virtual Versions of Real-world Activities–tidier, simpler, safer…but no substitute

Is there any danger that parents will let virtual versions of activities edge out the originals, perhaps in the interests of ease and tidiness? I hope not. The things kids learn from doing things in the real world cannot be replaced by virtual activities.

Let me start with some examples of virtual versions of real-world activities.
First,  consider “Cooking Mama”, a video game in which one follows procedures to “cook” various dishes. My daughter enjoyed this game when she was younger, and incidentally learned a few things about what ingredients go into what. That’s fine. But I would hate for anyone to regard this as cooking practice. Chopping pretend carrots is very different from chopping real ones. Safer, of course, but chopping real carrots gives a child practice in dealing with the physical world–in handling a knife, he judges how to position food for safe chopping, how much pressure to use, and how to keep his fingers out of the way. Similarly, while a child can’t get burned sauteeing virtual onions, neither will he learn how to judge doneness by sight and smell, nor discover that it matters how much oil is in the pan and how high the heat is.
Second,  consider computer art programs, which have gotten very good at imitating the appearance of paint, charcoal, and other media.  Digital art is a medium in its own right, with its own unique possibilities, and worth doing for itself. But it uses skills different from those required when applying actual pigment to a surface. Using a paint-tip in an art program does not require a child to judge whether there is enough—or far too much—paint on the brush. You cannot break a stick of virtual charcoal by pressing too hard. And while art programs include techniques not available with physical media such as paint, they also restrict the child in other ways.  She cannot mess around,  applying paint with toothpicks, sponges, or other objects at hand, discovering new effects in the process. Of course, she also can’t get paint all over her clothes, the table, and the bathroom sink.
My third example is pets, which is what prompted this post. When my daughter was young, Webkinz were popular, and Tamagotchi, and there seemed to be many games that let you “keep” a virtual pet. We also had real pets, and I kept noticing the differences between a virtual pet and a real one. Real pets are messy—sometimes very messy!—and the consequences of neglecting them more serious. Real pets are also much less predictable, and this is both good and bad. Good when they do clever, funny things that we never expected, like meowing when someone sneezes. Bad when they decide to go outside the litter box, or lick the frosting off the gingerbread house. Our real pets had personalities and quirks that slowly revealed themselves—one cat bold and forever searching the floor for crumbs, the other timid and prone to chewing on things, whether pencils, fingers, or plastic bags. Virtual pets are tidier, cheaper, and don’t scratch, but they aren’t nearly as interesting.
Having considered some of the ways in which virtual activities differ from their originals, why do I think it matters?
I think it matters because we all need practice in basic skills in dealing with the physical world. We never know when we will need them. As adults, we sometimes need to pour a glass of juice without spilling. We sometimes need to stick things together (tape isn’t always the answer!). Knives are useful for all sorts of things. We may need to help a friend paint a room without dripping paint off our brush.
It also matters because any simulation is a simplification of the real world, and we need to learn to deal with complexity. Even if we follow a cake recipe strictly, we need to be prepared to deal with real world factors that don’t show up in the recipe. Some ovens run hot. Different cake pans may lead to more or less browning. The baking powder might be old.
In the case of pets, there is additional difference between virtual and real. Real pet care has consequences for a creature other than oneself.  In Sherry Turkle’s book Reclaiming Conversation, she touches briefly on robot companions and pets, as well as A.I. therapists—on virtual relationships, you might say. Her concern seems mainly that conversation with computers may take the place of conversation with actual people, resulting in less practice in conversation skills (and so less conversation between people). Pets don’t talk, so conversation skills isn’t what I’m concerned about. But there is a relationship between a real pet and a person. Pets have their own needs, their own preferences, and part of taking care of them is respecting that. They are also vulnerable—we put them in situations where they cannot take care of themselves. The guinea pigs can’t get their own water and greens. The dogs can’t go hunting. Taking care of a pet is exercising responsibility and practicing some kinds of relationship skills.**
I started this by asking whether there is any danger of virtual versions of activities taking the place of their real-world originals. People are spending a lot more time with computers, but that doesn’t necessarily mean the real-world activities are being replaced. There also seems to be a trend toward making activities simpler, easier, and with less clean-up—packaging art activities with pre-cut bits and easy instructions,  offering meals that are half-way prepared to save time and effort—but even simplified, those are still real-world activities. I don’t know. I guess time will tell.
Till next post.
**I’m not suggesting every kid needs a pet, any more than every kid needs to practice painting or cooking. Besides that, the idea of giving a kid a pet to teach them responsibility leaves out the fact that parents need to step in as well, lest the pet suffer. Nor is this the reason people have pets—pets are fun! Pets are (sometimes) cuddly!

The Mini-Backpack, Round Two

Some time ago, I sewed a mini-backpack that was loosely based on the mini-backpack I use regularly as a purse. I always meant to have another try, hoping to produce a mini-backpack that was more attractive, less floppy, and lined. Finally, here’s attempt number two.

The denim mini-backpack.

I think it came out pretty well, despite some problems during sewing. In the photo, it is stuffed to make it look better, but it retains some shape even empty. For one thing, I used plastic “string” from the string trimmer (e.g. Weed Whacker) to give the back edge some stiffness.

I did try a lining this time, though I didn’t line the entire inside. Ideally, the lining would have pockets. Maybe the next version will.

The problems I ran into varied from the difficulty of dealing with heavy denim (thank goodness for the sewing machine with walking foot!) to problems with measurements to getting the adjustable strap hardware to work.

Some of these measurements are wrong.

That last problem had a lot to do with the straps being made of heavy denim. I couldn’t figure out a way to make them without a thick ridge running down the strap somewhere. I have an idea for next time, though. I think I’ll try folding the sides in and having them meet in the middle without actually sewing them to each other. There’ll be a thin gap running down the center of the strap, but if I zigzag the sides together, maybe it won’t be constantly bending in half.

The other thing I want to say about this bag is that it is mostly reused material. The denim came from old jeans, the lining from an old sheet, and the zipper was salvaged from one of those plastic zip bags that bedding and curtains often sold in. The plastic “string” was from our old string trimmer. The new materials were the strap hardware, some seam binding to encase the “string”, and the iron-on crystals decorating the front.
