Hi,

last days I scripted another little particle effect. This time the particles stream from left- and right-hand side to the center of the image and thereafter float down from the top to the bottom.

So, if we bundle all that tasks, we obtain a nice kinda hour glass effect (wich explains the odd title of this post).

All this works by having ~92fps constantly, so I think this is nothing to sneeze at… 😉

I´ve posted the sources and some further info´s [here](http://www.dasprinzip.com/prinzipiell/2009/01/20/hour-glass/)…
