We've always been warm for One Rincon Hill's late-modernist form. For some reason, though, we failed to realize this darling accent of omission, located at the tip on the building's west side, is intentional. What fun!
See, we have been wondering just when they planned on sticking in the last panel at the top, because it's been like this for weeks. But after visiting their (annoying, Flash-based) site to see who we could call and nag, it looks like that that's the way it's supposed to be. And we love it. So whimsical!
