One of the handiest little utilities that I recently created for Bobo Explores Light was a simple class for executing a sequence of tasks, any tasks. At first I thought it was another over-engineered piece of code that I shouldn't have wasted any time on, but then I started using it all over the place - to load and unload pages, to script animated sequences, to break down concurrent interactions into small chunks that managed themselves, etc.
If this might be of interest to you, read more about it and download the code here: http://gamecollage.com/development/task-sequencer-or-how-i-was-lazy-to-learn-lua/
