If you want some cool geeky gifts, you should visit these websites.
We purchase a lot from http://www.thinkgeek.com so I would go there first. They have the coolest items ever.
Another site we found was http://www.superherostuff.com which I just happen to have
a child’s Christmas wish list from this site and its a mile long.
Soft Kitty Jacket, from The Big Bang Theory, on http://www.superherostuff.com
Super Cool Avengers Leash in Pink @ http://www.superherostuff.com
Or how about this, my 15 year old daughters bedding: go figure, she loves the Avengers 🙂
