I'm not sure what I've pressed but now when I go to select faces or verts of a polygonal object I get a yellow and red highlight that looks similar to verts or uv's around the object. The verts or faces I selected are no longer highlighted. If I try to move the selection the entire mesh deforms. For example if I attempt to move a vert in the X axis everything moves with it and deforms slightly as I move it. I have no earthly clue as to what I've done or what setting I'm in. What's more interesting is that if I select a different object and try to move its verts or faces it does the same thing so I'm figuring its a setting I've managed to flub.

Any thoughts?
