Here application and game from here.... Enjoy it!

TouchWiz4, the launcher on the Galaxy S II, has been ported for use on the Galaxy Tab on any deodexed Gingerbread ROM’s. The installation package is for Clockwork Mod 3 and can be installed quite easily.

Not only has it been ported, but mssmison hasn’t forgotten to edit a few things to optimise it specifically for use on the Galaxy Tab, including an edited XML file to support the larger screen, the ability to set the workspace to use 6 rows and 6 columns and the ability to add 5 shortcuts to the bottom bar.

Changes I made for the Tab:
Fixed XML's to support larger screen
Adjust size for workspace/edit screens
Set Launcher workspace to 6 rows/ 6 columns (fits good)
Set appdrawer to 6x6 layout as well
Adjusted to allow 5 shortcuts on bottom bar

How to install?
This is a CWM3 package, save to sd card, use recovery to install (choose zip from sdcard etc)
You must clear your dalvik cache after install.

Reboot, clear the application data for twlauncher to ensure it displays properly.

This is currenty setup for 240 dpi, I'm working on a version for 182dpi as I type.
*UPDATE*
Alright, I've attached the 182 version. Unfortunatly I just cannot get it to accept a grid any larger than 8x8.. though I suppose that's still 64 spaces right?
