A month ago, stressed at CeBIT, in a small break of flowing through lolcatspace, I ordered two excellent Glennz.com TShirts:

and

There was a minor problem with shipment, but Glennz answered to my customer request and handled it excellently – I can only recommend this shop! and their shirts. Good nerdware.
