I'm now creating another chemistry learning module in my area of Second Life - Chemist as Artist, where students are given a molecule (created by Hiro Sheridan's molecule rezzer), then they have to link the atoms & bonds together, make a copy, rotate each one to form two different orientations, and draw them in 2-D using solid lines, wedges and dashed lines. My hope is that students will begin to be able to do the reverse: look at a 2-D drawing and in their minds' eye be able to picture the 3-D molecule. Here is the powerpoint presentation, which you can also view in SL.
