and show in wedding party.But i don't have enough concept if anyone have the idea.I think it is great for me.
If u can't have idea rely for others.
You can also buy them VERY cheaply, probably less than the LED's would cost you!.
If you really wanted to make one?, my 8x8 LED matrix PIC tutorial would make an easy starting point - just add serial in and out, and design PCB's for it - then stack as many as you want in a row!.
