We have a daughter who is about 20 months old. She's got all these 'educational' toys (put the square block in the square hole etc), but she actually has more fun with a bunch of clothes pegs and a tea towel. These items do more than one thing and there is no 'right' way to play with the object....I really like that. Then I saw this guy playing a guitar on boing boing. He plays the guitar in a most unconventional way - it's his own way, but makes good music.
All of this makes me wonder whether we're producing too many 'cookie cutter' maps, the tools we have are virtually limitless in what they can do, but we tend to produce variations of the same maps over and over again.
