If you like that, make sure to also check out Greg Davill, the one whose LED cube inspired him to build one for himself. Greg built a twenty-sided LED dice from equilateral triangles for example [0]. Very recommended!

He's on Twitter and has a blog:

He also enjoys photographing PCBs and the "media" tab on his Twitter feed has lots of great electronics pics for that reason.
