This one is quite cubular (is that a word?). It is spiky (spikee?) all around as you can see as it spins.
This is a wip - still working out a design for the connections at each side.
This takes a lot of time and is very hard to fit together as the cube gets more crowded the more you add spikes to it.
I tried to keep a "greenish/blue" color scheme going, but this slows down the process even more.
