i did one for my brother this christmas. hes 17 and really into halo so i did a 7foot by 4 foot poster to hang in the basement. turned out really well. went out and bought label paper so its sticky on the back and bought some mdf to stick it to and some trim to enclose it. i'll take a pic tomorrow maybe if you guys wanna see it.
I'd like to do a military one...something that can evoke emotion out of it. I lost that one thread at militarypictures.com. That thread had some amazing pictures in it.
Thanks for the link! My roomate and i decided to do one of our walls up in this. Now we just need some ideas for it. Maybe a giant picture of ned's face.
