High speed b/w patterns - Pico vs Lightcrafter

I bought a Pico 2.0, but have yet to get it to work. I'd be happy to buy the LightCrafter or other product, but since I didnt get the right thing previously, I thought I better ask about my application before buying the next part.

I want to run some perceptual tests on what humans see with various b/w patterns at high speeds. Ideal things I need:

• Controllable speed. I'll settle for constant 1000Hz+ and the ability to simply double/triple/etc frames to get 500Hz/333Hz/250Hz/200Hz/166Hz, etc, but actually setting the frame rate would be great.
• True b/w patterns would be preferable with RGB LEDs all simultaneously on, but I could settle for single LED monochrome. I dont prefer high speed RGB in sequence since thats complicating my perceptual experiment. 
• Easy way to control the device. I prefer to run it from my Win7 laptop. I bought a Pico2.0, but have yet to get a BeagleBoard and whatever else is needed. A simple Win7 GUI that lets me set patterns and frame rate would make me happy. Ideally its 5 minutes from plugging things in to messing around with patterns, instead of a long process of install this and that.
• Ability to turn off all gamma and other non-linear mappings. I want to be able to drive the display with inverted patterns which should sum to an even grey field when they are above the human flicker fusion threshold. For B/W this shouldnt be an issue, but if there is a greyscale mode, then I want the integrated light output of the two frames 0x00/0xFF to be the same as the 0xF0/0xF0. This isn't true when there is gamma processing happening between the input values and the actual light output.
