If I understand you correctly, that program should do what you want – at least start a normal application:


This is a simple screen saver for Mac OS X version 1.3+ that launches a regular Mac application, or a Unix executable, of your choice when the screen saver starts.

Exactly what was needed, Thanks! – Nickolas Whiting May 4 '12 at 17:24
Excellent little App.. use it with in combination with "Purge" to "reclaim" some memory in Lion (it tends to eat a lot and I go really low in memory some times) when my computer goes to screen-saver (and I am not actively using it - this is nice because it always takes 10/15 seconds to execute purge). – emgsilva Oct 10 '13 at 12:21
