Posters / tech stuff for classroom

Don't know if this is in the right forum but just started teaching programming in my old highschool. Looking for some cool posters/ tech stuff to hang around the room. Can't seem to find anything cool around my house because I throw out stuff for space :/ anywhere I could pick up some stuff and posters.

Dept. chair wants us to 'decorate' the room lol.
