It's mostly C/C++, the java consists of a couple of classes to set thing
up and provide the gl context - similarly to the glut app in the main
version.

I realise I forgot to add the java src directory to git, just fixed:

One idea is to expose all the sensors to the fluxus script and port
scheme bricks so you can plug them together somehow. This is going to be
a bit of a research project so it might take a while.

The biggest problem at the moment is that tinyscheme is really too slow
for what we need for every-frame type of work. (if you run the current
apk you'll see what I mean) I've got so used to racket's multiple jit's
and advanced optimisation mechanisms.

I'm starting to consider clojure again as a possibility, but this was
quite slow too when I tried it on android 6 months ago. 

I guess one obvious approach is to work on an android ndk port of the
racket core, which doesn't sound too hard for what we'd need (it's been
ported to iOS):
