This is what 15 minutes free during lunch will get you. Trouble.
Cables, plaits and braids from Elizabeth Dimbleby. She has even more free stuff here.
And if you're wanting to combine sock knitting with Aran designs, John Anderson's Kilt Hose by Robert Jenkins.
A bit late to find it, here's a Christmas stocking with an Aran pattern. (Scroll down the page a bit to see it, when you go there.)
The almost end-all-be-all of Aran patterns is at Knitting Pattern Central. Type in "aran" (without the quotation marks) and it will pull up the patterns for you.
Finally, some history of the Aran sweater.
