http://www.tropic.org.uk/~crispin/quantum/ Upside: it's got a quantum physics game engine, and can teach you quantum mechanics Downside: HN will continue to tear me apart for making them download a JAR file but you can grab the source and compile it yourself if you like
Looks cool. I'd love to be able to see more screenshots of the game - at the moment they're faded out and placed in the background, and when you click them you end up just downloading the game itself. I actually don't mind the JAR file thing ;) but I'm unlikely to download and try it without knowing a bit more about the game concept.

I'd hope the title explains the concept fairly concisely. It's a marble maze type game i.e. guide a marble towards a goal, stay out of traps. But the marble is quantum which means it looks more like a cloud and behaves nothing like a marble. This led to the levels looking less, well, maze-like than I'd hoped, but you've got to run with what you got, so I started bringing features into gameplay that wouldn't exist in a marble maze e.g. trying to fulfill multiple goals at once by getting orbits into a certain shape.
One thing you can say about my side projects is that they have been 100% out of touch with commercial reality (excepting a rock climbing website from the late 90s that made me a few k before I retired it)! I thought initially that some game studio might want to put money into developing Quantum Marble Maze beyond proof of concept into something more, but I guess either nobody has heard of it, because my promotion or delivery is somewhat lacking, or they're not that interested in something so experimental. Hell, even after open sourcing it I haven't had anybody contribute. According to the server logs only about 1000 people have even played QMM, and 10 people finished, which makes it considerably more niche than I had hoped for a project which tries to explain a truth "far more marvellous ... than any artists of the past imagined". Good thing I enjoyed the project for its own sake :)
