Is this frame safe to ride?

I had a head on collision once, but I was fine, picked my self up and got back on my bike. I gave my cranks, and wheels a quick look over, but since they were fine, I assumed my frame must be as well. After ten minutes of riding I needed to brake sharply, as I put on the front brake, the damage to my frame, which must have been similar to yours, caused the down tube to bend even more, my front wheel hit the down tube, and stopped dead, and I was thrown over the top of the handlebars.
So in conclusion, don't ride the frame.

That's what I'm basically afraid of.. I don't have brakes yet, since I just learned to skid properly, but I don't think I'll mount them on this frame, I'll try to get another one instead..doubt I'll get such a nice one though..

Another question, does the fork look bent near the lower cup of the headset? If it isn't then I'll use it on another frame, though if it is then I guess it has to go as well..
