You might remember when we reported on Blender's accepted Google Summer of Code (GSoC) projects for 2006. There were three accepted through Blender Foundation, and a fourth accepted through Python. Recently, a development build has been posted with the progress of Nicholas Bishop's project entitled "Interactive Sculpting with Multi-Resolution Models" (Nicholas is also the author of Sharpconstruct, which makes him the right man for the job for a project like this). Rather than describing the build, we decided to show you!
Keep in mind that the build I use here is in the very early stages and may crash every so often because of that fact. I also mention where I got it, so I will link to the thread by lguillaume here, and I will and the direct link to the files here.
