As a newbie looking for good example coding styles - I'd definitely prefer if this were coded for the "normal" case, rather than made special for the "no long running actions" case. I really appreciate this code, by the way. One of my biggest barriers to using Clojure is the terseness of the examples - stuff like http://clojure.org/agents#toc , while nice and concise, is quite off-putting for people used to more readable coding styles. - Korny > >> >> > while cleanly painting the board; the two thread >> > approach flickers terribly when the snake is short. >> >> I could be wrong, but I don't think that flicker is related to my >> choice of doing the painting off the EDT.
