Want to play with PowerPivot (Project Gemini) without going through the hassle of installing Office, SharePoint, etc? Try the newly released virtual lab!

Update: Slight bummage: This virtual lab allows you to play with client-side Gemini functionality only – no publish to MOSS and seeing what your results look like….Still a very good lab, though.
