I'm trying to hand-paint gameboards (five 21cm x 29cm boards, for a boardgame) for someone, except I can't figure out what material can hold up to the dual stresses of being painted/printed on (not by computer, but by the older methods of linocuts or woodblocks or etching) and the day-to-day wear and tear from being used as a gameboard, while still being reasonably priced. Can you help? [more inside]

In the Star Trek TNG ep, The Nth degree
, the Cytherian has an interesting material as his 'third eye'. I've had two tiles of it as a kid. It doesn't appear to be a hologram, but looking at it at different angles one sees a lattice of circles/spheres. What is this material and where can I purchase it in larger areas?

My wife is planning on learning to draw from the book "Drawing on the Right Side of the Brain" by Betty Edwards.
I'd like to surprise her with a box with all the materials that are needed to complete the course but I can't get the book away from her for long enough without her being suspicious. I've tried google but no luck. Does any one have or can direct me to a list of the materials needed?

I have a leak in my coffee pot's water tank, and upon examination, I cant see where the leak is coming from (meaning that the whole bottom generally gets too wet to detect the crack). I was thinking I would run a thin bead of some kind of material around the bottom of the tank to attempt to seal it back up. My question is: what kind of material would you recommend that would not pose any toxin problem in case the tank water comes into contact with it? It would also have to be generally heat tolerant as the coffee pot heats up under there.

Set designers, cinematographers, hobbyists, LARP people, carpenters, welders, and geeks: I need tips and tricks for building a one-person "space shuttle" out of cheap materials. It's for an independent HD video sci-fi short, and I would like to build it myself. Budget is $600–$1500 for materials and in-store material cutting/processing. [more inside]

I am taking an intro to materials science class, and in which we have learned about Miller indices, which are a way of denoting directions and planes in a unit cell. So far we have done nothing with this other than draw directions and planes. I was wondering, is this just a notational convention or is there some reason
why they are the way they are, as in does it make some more advanced math easier or something?

I'm looking for a forum that hosts discussion in the field of condensed matter physics and/or materials science. I'd like a site where scientists can go to ask and answer questions, similar to Ask.Metafilter, but a general forum would be good as well. Does anyone know of such a site?

"In order to feasibly produce, say, transparent adhesive tape, integrated circuits or sugar-free soft drinks, you need such-and-such materials and such-and-such equipment, which in turn depend on other things, all the way down to ores and fuel and such. So if you want to build your very own set of night vision goggles from scratch, here's everything you need access to in order to get started" Has anyone compiled, for the public to see, anything resembling a real-life 'tech-tree', akin to what's found in computer games such as Civilization?

What's the proper name for that kind of image-switching material that switches between two pictures as you tilt it? I mostly associate it with novelty baseball cards, toys, children's books, and so forth. That plastic-y corrugated stuff? If I wanted to order a bunch of postcards printed with it, what am I looking for?

You can make an interesting "fabric" (tutorial here
