The pixel# section is all about the graphical side of Pd. This is the place to get help with all things related to GEM, pdp, pidip, and GridFlow. Most of the stuff in technical issues is audio related, so this is the place for you Pd-ers out there that work more with visuals.
When posting a patch, just be sure to mention which graphics libraries it uses, as pidip and GridFlow are not included in Pd-extended.
