A powerful programming language built to be easy for children to use. LOGO is essentially a dialect of LISP without the parentheses that traditional LISP requires. It has been implemented in many versions including Brian Harvey's UCBLogo and the multimedia authoring toolkit called Hyperstudio.
There are lessons to be learned in all of these systems if OLPC application developers wish to stand on the shoulders of giants rather than reinvent the wheel over and over again.
Variations
Needs a better GUI (Brian Harvey is working on one, but he is working on it alone and as a hobby). It can be translated (without recompilation) to languages that have their character sets in 1 byte encodings. It was been translated to Spanish (LogoES)
Needs testing, packaging and materials (maybe it's still too beta)
Needs a migration to Linux. Has lots of learning material on the Internet
Needs a migration to Linux
Works under Python (which, it seems, will be a given in the laptop). Is this enough Logo?
Runs under Squeak (whick is bulky?). Is this enough Logo?
Freeware, but not open source. Requires Java. Actively developed; high quality.
