Im looking for a product. I saw a countertop that was interesting. It has all sorts of tiny squares in it and when you ran your hand over it, blocking the light, the sqares darkened, and not just where you block the light. It is very dynamic, and must use reflective tubes between squares under the counter surface. What is this material called?

I am looking to get a bicycle to ride around campus on. I was looking on craigs list and found a nice old Raleigh Grand Prix. At $65 it looks like a great deal. I don't want a crappy wal-mart bike that will fall apart after a year. This bike looks sturdy and has already lasted almost 40 years. I'm just looking for a 2nd, 3rd and even a 4th opinion. It is a fixed gear at the moment but i would plan on cleaning it up a bit and re-installing the gears.
