HTC made him take down the first version because it was identical to their own flip clock. He redid the widget and released it again, but HTC contacted him a second time and requested that he take it down from the Market until they have reviewed the new look. I looks nothing like HTC's clock now, so it should be back up soon (I would hope by the new year).
Do a search around the internet and you can find the 2.36 version -- which although not the latest, is the last Hero-like release -- and IMO -- is still the best.
