I am sorry for not posting a schematic. The problem is, I don't exactly have a schematic of my own, I have followed this diagram for an 8x8x8 led cube. I have basically wired them the same, but there are 6 shift registers instead of 9. And also one transistor instead of a pair of transistors, because by my calculations one should handle the collector current.
Hope this helps.
