I've provided a number of personalised geek hug templates in various forms below, feel free to distribute them as you like--but please note that they're all distributed under the terms of the GPL, so any derivative hugs must be free, as must any second, third (etc.) generation derivative hugs.
All the hugs below are tailored to you personally, if you would like to re-use them, just change the names and parameters.
I'd like to feature a java hug for completeness, but I don't know any java; if you have a java hug (or any other type of hug) you'd be willing to contribute, please contact me in the normal way.
Finally, Don't forget to check out the exclusive hug links at the bottom of the page.
