Bulb matrix for video clip

This is a bulb matrix that i have made for the use of this video clip during the time of one week http://www.youtube.com/watch?v=e0v6_EivxoI Not happy enough because did not have enough time to finish it like I wanted ( every bulb could be lighted up separately through application that I wrote in c# ) but will finish it later on

Looks good. Any details on the hardware and software used?

i used relays to turn on/off the lights, actually i have 225 of them but like i said couldnt finish this project in one week so here there is only 15 of them + shift registers + bc337 transistor some diodes resistors, the communication between pc and arduino was easy because i had 15x1 pixels bitmaps, and iterating through those bitmap sequences was like rising 2 to power of the pixel number if the color is black what meant that the light should be on, end send it through usb, to arduino, where shiftout library did the rest.

Cool project, came out looking great.
