I've been working on a computer-controlled air-powered press the last two weeks, and now things are finally sort of working we need drawings and schematics.

Re: Good program for drawing coordination structures?

MarvinSketch is pretty decent and free (as in beer unfortunately). And Java, so kind off cross platform and easy to try. Chemsketch does coordinating bonds, but I can't recall if it did that many. Probably did, but auto-clean becomes real messy real fast.

Re: Breathing Water - At all possible?

Main problem with any liquid is that your lungs (and your chest muscles) won't be strong enough to move it, and carbon dioxide doesn't diffuse fast enough, no matter how much oxygen you pump into the liquid. I don't think anything will change in that anytime soon..
