I blame LOGO for opening my programming mindset beyond the confines of BASIC on a VIC-20. In 1986, that was the only tool readily available to me until an after-school class introduced me and other interested kids a bunch of computer stuff, including LOGO.

It's a bit rough around some edges, but http://turtleacademy.com/ is a decent site for introducing people of all ages to LOGO.

I love what a few minutes of casually messing around in LOGO can lead to: http://turtleacademy.com/program/update/53767042f4585906683c...
