How to, or where to find instructions on making a computer controlled LED plate?

Hello, I would like to know were I could find, or if anyone knows how to make a plate of LED's [so a flat surface with LED's embedded], which I would be able to connect to a computer [either via a cable such as USB or an integrated small computer such as the Rasbery pi], so as I could on the computer change which LED's were lit?
Personally I know nothing about this material but I am very eager to lean, realizing that this is a fairly complicated project is their a product on the market like this, and what would be some good simple projects that would help me to start learning? Thank you

there has been an instructable posted on that very subject no 2 days ago,

Buy the LED plate and add a microprocessor.  I did this long ago.

Any micro controller like an arduino or pic will be able to handle that sort of thing for you. Wiring it up is the easy part. The hard part comes in programming the controller to take the commands you want to give it from the PC and execute the pasterns you want with the LEDs. So head on over to the Arduino web site and start learning about them.
