Simple brain exercise that may boost your short term memory (open-source, feel free to tinker with it)

Mine is less faithful to the original though (but still has the visual and auditory component) and is not very fancy or polished. On the plus side, it's only 70 lines of code and runs on Ubuntu :-)

I get an error called "NBack has encountered a problem and needs to close."

Edit: Same problem on a Vista system. I know this isn't a tech support forum, but I wanted to let other readers know that they aren't alone if they're encountering troubles.
