Here's a Perl on Android demo, courtesy of my Cross-Compiling grant, Object-Remote (git repo) (Matt Trout and a bunch of contributors), and James' java-implementation using the same protocol: Object-Remote-Java.
This demo loads (eventually, it's a bit slow) a simple EditText box and a button. which is created using Perl, at runtime. The button can be used to choose a file, and the contents will be loaded into the EditText box, via a callback that is also written in Perl. The file choosing needs the OI File Manager or similar installed on your device.
Challenge: Add code to the demo Perl program, installed in uk.me.jandj.runPerl/runperl.pl to make it able to save changes made to the opened file. Add more useful things if you like. Highlighting? New files? Templates?
A 3D print of your choice (as long as it's not a huge one) to the most complete (chosen by me) code, by January 15th.
And now I have to write some documentation...
