This is the awesomest thing ever.
At the scripps aquarium near San Diego, they devote half the space to teaching kids about science. In a wing devoted to explaining gene expression they had some stuff about DNA and the coolest thing was this video game that taught you about building blocks of life, then proceeded to a real DDR game where you have to step to the DNA parts being shown on screen.
The best part was when one of the 20 amino acids were built, it would say the name. So you'd see A T T G C and so on... and then it would shout "Cysteine!"
