I can relate to the joys of seeing something finally work after some tedium. I guess programming isn't quite like art or music, but the thrills of creation are there all the same, you know?
Of course, there's also the similar feeling: the uneasy feeling when something works but when you examine the code you aren't sure why it does...
A 'tech demo' of wandering and interacting is still impressive work, especially for a week's time and learning your tools from scratch. You should be pleased with yourself.
