I’ve made a direct mac port, it’s available here:

OSX 10.5 (2.3MB)

It’s identical to the windows one. I had been meaning to tidy up both a little bit before this release, but I haven’t had time.

Also, I’d like to say that I had a lot of fun this competition and, though it took some not inconsiderable amount of time time, and also playing through what entries I could; some really beautiful stuff came out of this competition. I look forward to the next one…
