TLC5940 software

I just came across this:

"LED Frame Designer Software allows the user to individually control the Dot Correction and PWM dimming levels for each LED on the TLC59xx EVM. The software also allows the user to program and play multiple LED “frames” to create different lighting patterns on the EVM."

Have anyone looked into this for TLC5940s?

Ok, that flashes a couple of gears, then goes to an all black screen. Not really helpful.
