Whats Next?

Whoo Hoo!  I've got all 8 layers soldered together.  It looks really cool and is super stable.  It was a lot of fun to build.  Here is a picture:

The rest of the parts arrived, here is a shot of them:

I also put together the USBTinyISP device.  I didn't take any pictures of it so if you want to see some just take a glance at the instructions I followed, they have tons of pictures and mine look very similar (only a little 'cleaner') ;) :  http://www.ladyada.net/make/usbtinyisp/solder.html

Next I guess I'll start working on the electronics for the cube itself.  I'll post pictures of that as I make progress.

This is the most fun I've had with electronics in a long time.
