Twitter employees have been uploading pictures of their new digs in San Francisco. Looks like the microblogging startup is more concerned with catching up to its rapid growth than with coherent interior decoration.

It's hard to blame them. Still, some of the pictures compiled by TechCrunch — from Twitter, naturally — have us scratching our heads. Click on any of the first three items in the gallery below to see what we mean.

The mirror in the toilet stall. Bill Farner, who took this shot, is confused about this oddly-located "vanity" mirror's purpose. Can't say we blame him!

The lone "at" symbol on this wall. Wouldn't "@wall" be more appropriate? Or "@couch!"By Ryan King.

The DJ booth in the dining room. It's not just lunch, it's a party! By @caroline.

DJ booth in context (it's in the back). By Bill Farner.

This isn't one of the "weird" things, but it's noteworthy because of the subject: That's Ev Williams' wife Sara Morishige. So this, presumably, is the CEO's own office. Anyone know what the "795" is about? In any case, it's generous of the new mom and longtime designer to handle the interior of her husband's office. That's going to be a crowded wall, judging from the density of what's up so far. By @caroline.
