Spent a productive day kinda getting to grips better with the object functions, arrays (and iterating through them), and the dist function in processing. With a decent sized shout out to Mike for some tweeking of code to actually make the bastard work I managed to get some quite pretty results. The top stuff is a proximity sort of thing each time a new point is drawn it assesses how far away the other points are from it and draws a darker line depending on how close it is to a given point. Pretty. The second set is a simple (but triumphant for me!) distance thing done earlier on in the day where it assesses how far a new point is and if it's within a certain range draws a line to the middle of the sketch. I felt well good after doing these- looking forward to doing some more. (code to follow when i figure out how to do it!)
