Yes, I remember that project. It was called The Gotham. There was a big story about it in the Austin Chronicle featuring the rendering on the front page. I still have it stashed away. I remember the developer put his foot in his mouth when he commented about the bats under the Congress Avenue Bridge, and commented on how they weren't sure how to get rid of them. I think at that point the guy didn't have a chance in Austin.
By the way, a residential project was later built in Houston by the same name. The design is very similar to that building, borrowing its Greek style architecture. If you Google "The Gotham Condominiums, Austin, Texas" you'll find a few more images of it.
Here are two links showing the building in Houston. I'm wondering if this was the same developer. Surely it's at least the same architect, since the architecture firm would have owned the design.
