I was surfing over on Lifehacker a couple days ago and noticed a program called BabySplat. It’s a wonderful little program that will put random lines or shapes on the screen and play a noise with any key press.
Julia was facinated by the noise and the lines/shapes. But she kept holding down the keys and the program kept on putting more lines and shapes down, and made only the first bits of noise. Still, it got us quite the laugh to see Julia staring down the lines as they popped up on the screen.
