I'm experimenting right now with the driver and I'm finding 80ma a nice
brightness and still within the spec of the LEDs.

I'm going to be multiplexing the display as either 22 row or 11 row
groups and updating at 70-100hz.  This means that the MOST LEDs on at
any time is 960 or 1728.  1728 LEDs at 80ma is 138A or 691 watts.  276
watts of that would be heat.  ;)  Not bad...
