A few people have asked for links to sample BISM data models and reports to demo Project Crescent or Power View.
There are two main choices
1. The official site has a Hello World Picnic or Adventure Works examples which are quite cute

2. You can download an entire VHD (needs Hyper-V) that contains the whole stack including the TailSpin Toys database, BISM project and sample reports. Be warned this is 60GB or so.

I’m using the Tailspin toys are the moment, but the Hello World Picnic is a much smaller download if you are not using the massive CTP image/VHD.
HTH,
