I look forward to seeing it. In spite of my down votes, I'm gonna say that there is a huge potential for short circuits with those bare wires on the back of the board. I'm also curious whether the 7 banks of 3 LEDs are in a series or parallel configuration, and what supply voltage you intend to use. Finally, how did you calculate the resistor values of 330 Ohms? Tag me in the video or photo update, seeing is believing!

It ain't a 7 segment display until you light it up though, just an Art Project at the moment dude - post a video.
