LXlogo is a variant of the LOGO language. Logo is interesting because it gives students immediate graphical results with just a few commands or lines of code, and allows students to gradually become familiar with geometric concepts, and how to write programs and think procedurally. As students move beyond the beginning stages, they can move on to create fun animations and user interfaces.

Most students today are very familiar with how to play video games and use applications, but have never experienced the thrill of having complete control over the computer like they can when they progam in a language like LXlogo.

LXlogo became available in Spring of 2005. I wrote it because my 11 year old son enjoyed using a commercial Windows LOGO package at school, but there didn't seem to be any Linux LOGO packages around that I could get to do what I wanted on our home RedHat box. LOGO has been around for a long time, but there seems to be no published LOGO standard. So portions of LXlogo's language have been modified when compared with other existing LOGO systems.
