Use an oscilloscope-like visualizer in iTunes
I'm the creator of Soundstream and iVestream. Soundstream is the original screensaver that prompted the creation of the iTunes visualizer, so they share most of the code.
In response to TGV, the Check on Fridays patch is a part of the screensaver that checks for software updates. It only checks based on certain factors (automatic update checking is enabled, it's a Friday, and the composition has been running for at least 5 minutes). Also, since it uses similar RSS technology as Safari, it does not continuously poll the software update server. In Scope.qtz and iVestream, the automatic update checking is disabled, so these should never attempt to connect to the internet. For simplicity's sake, the other patches were left in there. It is true that they continuously check whether it is a Friday and should be removed for best peformance, but Quartz Composer has several optimizations that minimize the negative effect of these patches. I have offered to work with knifehandchop and improve the performance and layout of the oscilloscope composition; I expect one of us will post a link to the improved version once it is complete! Finally, I thought I'd point out a similar compositions-in-iTunes product: Jax by Prosoft. |
