I'm pleased to publically announce a little project I've worked on. Based on a recent research paper [0] that claims fluid intelligence could be improved by training working memory, I wrote up a dual n-back test memory game in Haskell and gtk2hs. This is still essentially an alpha release: all comments are most welcome.
