I must have deleted two of the icons you picked because there's blank spaces, LOL. I had to make more room for the icons I'm sure are to come after tonight! For the ones that are still up:

Rocket boy - was made for me by prettypinkdork. She had an icon request post where she said she'd pick an interest and make an icon. She picked Homer Hickham, who is a NASA engineer who built rockets as a kid. See October Sky. :D

Sk8ter boy - I don't make many SGA icons, mostly because there are plenty of other people who do a way better job. But I had to have one relating to Flanigan and his love of skateboards.

Cylon beating heart - ummm... I stole this one from whyoffry, who snagged from...someone that I can't remember right now. It replaced my old Cylon icon of the two Centurions with the little heart in the center of them. 'cause Cylons are LOVE!
