hereŽs a patch for creating a line in Gem by ramdom-coordinates for x et y. itŽs far away from perfect or something, but i am a beginner, so, please donŽt laught :) I donŽtknow if it will work just as an attachment, if not how would it be the best way to post to the community? thanks for your links and hints on fractals in Gem! I will ave a look at them the naxt days and maybe I will have success ;) another question: were can I find all the different libraries for Pd? when i load up pd, I get the message from some libraries: "canŽt load library". Cheers, Johannes
