Zac White is relatively new to Cocoa (but he is getting better!). He has only made a couple programs, the newest being SearchMagic. Try out the alpha on the software site below. He started a company called Positron Software that did some random programs for a while. This company has kind of merged into http://zacwhite.com/. The best way to contact Zac is by AIM. His screenname is 'cubeman'.
