Sorry this isn't an answer, just noise, but for those here who don't know, Bruce is the chief maintainer of the vpython project. I have found vpython aka the visual module to be a highly attractive and useful module for teaching physics. It would be great if someone with Boost experience would try to help him out. I wouldn't want him to get falsely disillusioned with this list as I for one have been looking forward to a fully numpy-compatible version of vpython.
