Hi

You can do something similar by placing a finger over the camera and shining a light on your finger.

Unfortunately TurtleArt is a little slow to capture your pulse, the following executes a cycle in about 0.5 sec on a XO1.5

forever
 show camera
 read pixel
 show heap
 empty heap

This prints the rgb of one pixel centre image ( which is OK because the image is out of focus)

forever
 print brightness  

averages over the image and takes round 2 seconds
