A while ago Alex pointed me to this site about how to make your own cute pixel objects. I messed around a bit and came up with this:

Hey, it’s a start! It also came to me that you could write code to do this for you. Some kind of PHP module with methods like:

pixelcube(dim_x,dim_y,colour);

You could have a pixel objects graphics library with all the basic primitives like cube, sphere etc. Hrm.
