ok, this may be in the wrong forum... but you guys there seem to be a bright bunch and i dont know where else to ask for help...
what can be used to control appx 200 LED "grids" where each grid contains a set number of LED's...
2 main function of light control, stay lit, and sparkle in "random" patterns...
thanks...

Depends on how the LED's are hooked up. Explain more.

It would take something like two sixteen bit registers arranged x-y (256 LEDs max) and a micro controller like BASIC Stamp to address them. Simple enough if you have an electronics background but a bit out of reach if you don't.
There might actually be some ready-made kits out there for that very purpose but I don't know of any.

thank you for your replies...
i know my original question was vague...
ok, you guys see those ceiling panels in the office spaces? (you looked, right? :D ) the grids will be in similar format...
2' x 2' panels with LED lights installed.
the panel grid will have LED's of varying density (for artistic purposes)
4 LED @ 2x2 grid
16 LED @ 4x4 grid
36 LED @ 6x6 grid
64 LED @ 8x8 grid
100 LED @ 10x10 grid
so basically, sections of the grids will have varying densities...
the LED's will have 2 basic functions...
1) all on/off
2) sparkle where "random" LED's will turn on/off to simulate a sparkling effect when viewed in whole.
i dont intend to control the entire LED's but just select ones... say 1~4 per grid depending on density of grid.
i am looking for an already made solution if possible.
any thoughts?
or just some key words so i can google it?

yes! the best way would be to use a micro controller.
like what real genius said, it might not be the easiest for most people, but for a EE or electronics fan, it's definitely do-able.

Check those guys out. I've bought from them before when I was doing some LED/wiring stuffs.
They have a huge selection to choose from and are a pretty nice webstore.
