Randomly Generated Field of Spikes
thingiverse
Basically like what the name says, it is a field of randomly generated spikes of randomly generated colors. Their height is based off of each spike's color value. I uploaded the OpenSCAD file, so you may screw around with it as you wish. I have not actually tried to print this, but it may be possible, if you change the amount of spikes to something around 30 by 30.
