Steven Leckart spotted this most excellent blog: Thumbs & Ammo. The conceit? Replace the guns in famous famous movie stills with thumbs. The motto? "Real tough guys don't need guns, they just need a positive, can-do attitude." Beyond the blog, you can follow them on Twitter: @thumbsandammo.
Say what you will, but I still love some good Photoshop culture jamming.
