Hi Christoph

I have never done such stuff with R (and I don't know, e.g. how good the
timing would be, in case you are interested in reaction times and so on)

but have a look at 


it's a stimulus-presentation framework, written by Andrew Straw entirely
in python and has lots of great features.



P.S please let me know if you succeed with a solution in R!
