isomap

In cartography, the isomap is a map made of contour lines (also isoline,or  isopleth) joining points of equal elevation (height) above a given level, such as the sea level for a landscape. 

We can use this technique to map the topography of our body, and we choose instead of the sea, the floor as the given level.

Score:

You can make the Iso map of any part of your body, (or of your whole body). To do this score it's easier to be two people:

One person takes their clothes off and place on the floor the body part they want to map. The other person uses a make-up pen to draw horizontal lines on the body parts, each line needs to have an equal distance between them. (for example if the first line is one centimeter above the floor, the second line will be 1 cm above the first line and so on). 

When this is done, take a picture from above. This is your Isomap.
