ok have each "plane" of led's on a seporate ground go there is 10 wires which are ground each line is attatched to a switch of some sort so only one plane is grounded at one time. Now make each "stalk" (verticle line) have its own power supply. now you can chose which plane and which stalk there for allowing control over every single led individually. Now just like a monitor you have the controler light up only one led at a time but have to do it so fast that you do not notice that they are. Now all you have to do is program which led is comming on at what time and its duration. As for the controler itself you will have to use several chips eash one say controling a different colloum (a sheet of stalks) so you will use 10 chips. now each chip is programabol so you just program them to do what you want it is quite simple realy if you think about it.
