Step 5Electronics
Well& so I will explain briefly how I made this part& Each square has 8 red hight brightness leds inside no oriented upwards so the light difusses better. It makes 200 total leds, its a bit boring to solder so many leds& The control of these leds ia made with a PIC 16F876A Microcontroller. The control software is in C and I made a software in order to design the sequences. The sequences are changed via RS232 communication when I play music on Winamp I programmed a PlugIn that synchs the table with the music bpms& Maybe all the software stuff was one of the easiests and fastest to develope as I have long experience with the subject.
So& the PIC receives the signal via RS232 (I will make this communication via Zigbee when I get some Xbee modules) and transmits them thorugh I2C to PCF8574 that make use of the ULN28003 in order to get enough current to feed the leds&
So here are some pictures of the soldering process (It was quiet boring and the results are not very well looking, but none will see the soldered board):

Nice job.
Is possible to share the schema and Hex ( or MiKroC source file)
My best regards,
