I'm looking for (surprise!) the Embarcadero Center set of skyscrapers from San Francisco. Normally I wouldn't even bother posting this, since it doesn't seem to be in the LEX or STEX, but I remember once upon a time someone taking the project, and even posting a few screencaps of the BAT in progress. So, if anyone did happen to once upon a time start them, then cancel the project, I'd love to know.
I believe bixel started working on that project over at ST, but I don't recall him ever saying that it had been uploaded anywhere. I'll check.
EDIT: Bixel did in fact start working on the Embarcadero Center, but he hasn't released it. In fact, it doesn't look like he's worked on it for about a year, judging from his SF BAT thread.
