The old checkmark logo of the Amiga computer systems.

This logo was made from a simple greyscaled bumpmap converted to an object. As such you will see the whole model as a square, but only the checkmark has an altitude of more than 0. In effect, only the checkmark logo should print.

The bumpmap was not 100% smooth so some roughness is present and inclanations from edges are not perfect 90 degrees.
