Need a body weight workout?

My friend is on vacation for the break and so I've lost access to the garage where the weights are at. Now I'm going to have to substitute my usual weight lifting with body weight exercises for about a month. Can someone write me up a tough regimen that is pretty challenging? I've been through a little bit of the 300 spartan workout, pretty damn tough, but I'm looking to up the intensity to work on strength rather than endurance. Keep in mind I'm not trying to lose weight, so I want to eliminate cardio for the time being. Any help is appreciated and the person who gives me a reasonable regimen gets 10 points.
