As promised, I've put together the source for part one and two of the TransControls articles. Be sure to review both source files, as the source for the TransPanel is very different between the two projects (as outlined in the articles).
I'll be beginning on the next installment throughout the next week. It's kind of difficult to get my head wrapped around writing this this particular style (where I look like I'm making mistakes and pointing them out as the article progresses).
Download the source (located near the end of the articles) and let me know what you think ;-)
