Someone should do a good Randrome tutorial

[dvdrtldg]

I find this RE frustrating because I really want to make the best use of it, but the manual is hard to understand (for me) and while there's an interesting demonstration on YouTube, it doesn't go anywhere near unlocking the full potential of the device.

I can make it do basically what Randrome Jr does, but that's just scratching the surface. Anyone care to throw out some ideas?
