Somebody made a video of grid

The gridding doesn’t actually start until about half way through.

Grid install instructions

Install build dependencies (platform specific) perhaps something like:

sudo apt-get install libtool compiz-dev compizconfig-settings-manager compiz-bcop

git clone git://anongit.compiz-fusion.org/users/stevek/grid
make
# if you get build errors you may need to install more dependencies and make again
make install # you can install as a normal user into your ~/.compiz folder

Enable grid in the compiz settings manager (ccsm)
