I opened my Gmail this morning and suddenly noticed it was a deeper shade of blue and some of the icons seemed to look different. Just to prove that I wasn't imagining things before my morning coffee, I opened my company's Google Apps mail, and sure enough, Gmail now has themes. Very cool.
On a completely unrelated note, I've been having a lot of trouble searching for stuff using Google. It always complains that the request looks like it's from an automated robot. I wonder if this is related to the great firewall of Thailand.
