The CTP1 of PivotViewer for Reporting Services has just shipped! Get your free download from here. As I was saying in an earlier post, it is a concept project. It's not supported, and not a feature.
However, it is really cool! It allows you to easily create stunning visualizations on top of your BI data - and these visualizations are fully dynamic: you decide at runtime which subset of data you should see, it shows the actual live numbers, and you decide how much (meta)data you associate with each card. Also, all of the cards are generated by the service, so it is very convenient. Of course it comes with sample data, and a tutorial.
I will continue to post articles here but if you have questions, I suggest you ask them on the PowerPivot forum. I will monitor it for questions related to PivotViewer for Reporting Services.
Videos will be posted soon - I'll keep you informed (also on twitter) about the location.
