[newbie]Led matrix

Hi :slight_smile:

I'm new to this world (I'm a freelance developper so hardware is not my thing), I'd like to make arduino project because it seems just awesome, I'm not sur what to do yet so I'm exploring possibilities.

Here's my question, what can be done with led matix? Can I build one? What are the limits? (The, still vague idea, would be to make that kind of thing: Reactive LED Coffee Table - Arduino 2 - YouTube .)

Thanks and sorry for my english
