Printing a Random Pattern on the desk Answered
A couple of weeks ago, I bought an Ativa (Office Depot store brand) wireless mouse on sale for $15. It appears that they were clearing out stock, because they no longer list it on their website, but this is the closest thing I've found. I like the mouse, particularly because there is a built-in charger in the wireless tranciever for the two Ni-MH AAAs it takes. Yes, AAAs, the link is for a different mouse.
Problem: Lousy resolution, I think. the wired Lenovomouse that came with my computer worked just fine on my smooth, blank desk surface, but this one requires much more of a pattern. I don't like mousepads. Scribbles with a pencil work well so far, but they smudge after a day or so. I want to put some sort of pattern on my desk for it to read. My best idea was a laser-cut random bitmap stencil and a can of black spray paint, but I don't have a laser cutter. Ideas?
