Here's an intriguing approach to edutainment and exergaming, found at the Birch Aquarium at Scripps (photo snapped last year by Flickr user mathowie). The dance pad's arrows are replaced with DNA nucleotides (shortened to A, T, G and C). The player creates one of 20 amino acids by tapping out the appropriate sequence shown on screen. If you successfully hit all of the nucleotides it would shout out the name of it (e.g. "Cysteine!"). Totally cool for the nerds in us all. Check out the highlights for today:
