I'm considering building a visual programming language , akin to Scratch , for use by children (a.k.a. poor typists) in programming micro-controllers or robots. There is, for example, a project to build a graphical programming environment for the Arduino . I really like Scratch, and would like the graphical coding to be similar. Scratches source is available under its own free license. It is written in Squeak (based on Smalltalk), and I don't know the language. It occurs to me there might be other projects to build off of. When I looked through Wikipedia's list of graphical languages, I didn't

My son is enthusiastically programming simple games in Scratch . However Scratch is a very simple programming environment (no subroutines even), and I can see that soon he is going to need to move on to something else. Does anyone know of a good learning language that makes graphics easy but provides "real" programming features like data structures, functions, arrays and lists? Bonus points if it runs under Linux (Ubuntu). An answer of the form "language Foo with library Bar" is also an option. Maiku Mori How about lua? There is nice graphic "engine" called LOVE which is fully programmable in
