Touch sensitive strobe ;)

I want to experiment with a touch sensitive switch (dar. pair) which I already tried and worked really well and a strobe, where I can control the frequency of an LED by adding the people closing the circuit from the collector to the base terminal. The schematic is attached.. I tried hard but the simulations weren't a success.

Someone can give me an idea? I assumed body resistance to be about 1MΩ and so I used an interactive potentiometer of 10MΩ. What do the 555 ic take from pin 6 and 7: voltage or current?
