Playing with Playwith- R Package for Interactive Data Visualizations

While just browsing through Google Code repositories for R Packages-

https://code.google.com/hosting/search?q=label:R

I came across Playwith- which is basically a toolkit for creating interactive data visualizations. I then played with ClusterApp and it really seems promising (hierarchical) – Since I am using R 2.12 on Win 7 (x64) platform somthing broke but overall this seemed like a promising interactive tool making widget.

playwith is an R package, providing a GTK+ graphical user interface for editing and interacting with R plots.

The playwith package is maintained by Felix Andrews <felix@nfrac.org>

Here is the Data Visualization called Cluster App that impressed me There is an obvious synergy between Rattle and Playwith (though some bugs with new R 2.12 on an X64 do come into play)
