EXP2 week2 independent study

The idea of the pachube feed is to link the number of people in a room to the brightness of lights. So, as the data goes up, more people enter the room. A flowgraph would show the intensity of lights and the number of people in the room. But if I change the idea of room and light, that could be more interesting. Also the effect of bright lights could be changed to something like brighter floor and this represents there are more people stand in that area.
