Hi all, sorry for the lag, have been without computer/internet access
for a while.

For now, we will just be unzipping the elements / box2d .egg libraries
into lib/ (until we figure out how to include setuptools from within
an activity).  Will commit this within the next few days.

Cheers,
Brian

I thought about this in my UI round, but other than tweaking the icon a little I didn't see a clear win. Happy to revise though if there's a consensus – I thought of changing the icon to several of links in a chain, but this would indicate the joint is made of flexible sections, when actually it is a solid rod with a pivot at each end.
