When I installed Visual Studio 2012 Express I noticed their nice loading animation in the bottom. See image below (found on web):
After a couple of hours, I'm sort of satisfied.
Just run the file called Loader Example.vi in the attached folder.
If you want to resize the cluster that contains all the moving objects, that should work just fine. And if you want to add more objects than 5 that should also work fine as long as you tweak the "slow speed area" (see code) setting. I imagine if you spend some more time, you can even make nice patterns in the y-direction.
Have fun and please post your improvements,
