Hi, new user here (via the Lifehacker how-to... testing multiple GReader alternatives and yours is winning)
Way back in the 1990's, I worked for a company named Tetra Tech. (It did various civil engineering services; I did databases to allow them to bill their services properly and profitably based on some whimsically written contracts; it was actually rather interesting) At one point I needed to make a template for invoices and since I thought their logo was kinda cheesy looking (and still is)
I decided to give it a graphical facelift
but I never could get them to adopt the design company-wide (dumb civil engineers).
Anyway, I would never want you to adopt even a nicer version of somebody else's logo (even if you have the same initials: TT), but when I was playing around with the design those many years ago, I thought of an interesting variation - instead of the small t nested in the capitol T, use a bigger 'small t' and a smaller 'capitol T'
Here it is shrunk to icon size
Not the greatest, but for something I spent a few minutes re-creating from an old memory, hey, how many other free logos have you been offered?
