I have a detachable CP and need to build a second. Thing is, I really want it to be very basic, essentially a large mouse pad. This one will have a USB port to plug in a mouse, and maybe two buttons on it to serve as mouse buttons. The rest will be empty.
The idea is to allow my kid to learn how to use the mouse while playing educatinal games.
So the question is, what are some ideas for overlays that will work well with an optical mouse? I don't want to get plexiglass or lexan since it will get scrathced up very quickly, and it's fairly expensive for what I'm looking to do with this cp.
