How about World of Goo for Android OS? What do you need GooTool without the Goo?

Quite!

The new GooTool architecture enables it to build a World that isn't necessarily a folder on your local computer... this is designed so you can run it on your PC and build a world to run on a remote device (e.g. an iPhone/iPad)... but this depends on World of Goo being released for them first!

I heard that Android is going to support Java in the future. I suppose it would be possible to port GooTool to the Android without too much effort. But if there's no World of Goo on Android, I don't see the use of having a native GooTool on Android.
