There's a new site about using the collaborative learning spaces at Boucke and Pollock at University Park at
http://tlt.its.psu.edu/learningspaces/
The idea is that students can get together in one space to work on team presentations or team projects. Some spaces allow you to share documents on one large monitor, and are comfy lounges with wireless.
If similar environments exist at other locations, we would love to know.
