Why Juice?

It was inspired by the extremely cool toy at www.sodaplay.com. I also thought their name was pretty cool, and I like juice more than soda, so I poached and perverted their moniker - it was originally Juiceplay. It could use a better name before I actually release it to the real world. I am entertaining suggestions...

Is the source code available?

Yes, but the license is rather restrictive so it can't properly be called an "open source" project. Basically, you're invited to download it and tinker with it, but you're not allowed to redistribute it. Juice is now part of my resume, and I believe it's more valuable in that context when it's a one-person project (plus the third-party libraries of course). If you would like to license the source under different terms, please contact me.

It runs on Windows, but what about Linux?

While I'd like to do a Linux port at some point, I'm not promising anything. The application logic was written with portability in mind, so that probably wouldn't be too hard. But, right now, my first priority is to get the Windows version fully developed... and I have a pretty lengthy to-do list already.

If anyone out there is using Wine, I'm curious how Juice runs on that platform. That might be a reasonable interim solution until a native Linux app comes together.

What are the units of measurement?

Good question. They're actually pretty arbitrary. I think of them in metric terms (length in meters, mass in kilograms, gravity in meters per second per second, etc) but I'm not sure that's right or wrong. According to the author of the physics library, they're just numbers as for as the software is concerned. I have mixed feelings about that interpretation, but who am I to argue?
