I’m looking for a couple images, One I would like to be the size of the avatars on any SMF forum, like here Java guru, Lisp guru, Moderator etc. This one though I would like to be “Tech guru” with a nerdy look cartoon or a laptop (Something that would correspond with tech work, just be creative :P) and the other I would like the size of the stars on here, but something tech related aswell, like a little wrench or something. I’m not creative at all so I need some help… If you have any other images you think would be good feel free to make them 
They also need to be transparent.
