Freeverse, the company behind many a fun Mac app, recently held a contest related to their vector illustration program, Lineform. The contest was simple: submit an image made with Lineform and you get a chance to win $1000. Not too shabby. The contest is over, and the winner was Paul Davidson.
You can see Paul's work, and the work of the runners up, on Freeverse's website. The original Lineform files are also available for download.
