The first audio sketchbook entry was posted on New Year's eve of 2002. So, just going by months, the last day of June is the six month anniversary. My goal was to produce about one sketch a week, which would mean I would need to post #27 today.

However, in celebration of the half-year anniversary (and to make up for the fact it's been over a week since the last post, due to the programming competition), I figure you deserve a present.
