This is a pretty cool concept, I wish the video gave a little more detail about Heart bot though. Heart Bot is an experimental drawing machine created by Intel, SMS Audio and Sid Lee.  The robotic drawing machine was built as a promotional piece for the Biosport headphone line and launched  at The New Museum in NYC. The Heart Bot uses biometric feedback, specifically the heart rate of audience members to draw a series of lines on the wall. As audience members hold their hands on an interactive pedestal for about thirty seconds a sensor reads in data and track their heart rate. That information is sent to the robotic arms which draw the lines in real time.
