A quick update: version 0.46 is out ready for testing:
1) 'intro' param added, available for each effect and on by default -> at the moment it fades in the effect after the page has loaded, there will be more intros coming though
2) 'posterize' param for 'film-noir' added, check the demos
3) Debug toolbar (only performance can be checked at the moment)
4) Validation - the script will leave your browser alone if it cannot average 15 fps
Please have a look at demos / benchmarks
Looking forward to your feedback
