@Wolfenoctis:
Interesting idea -- like collision detection with invisible volumes. Are those more or less straight copies with the people removed, or significant adaptations?

Not sure if this is Sketch or OT-thread material, but thought I should share this exercise as it's been very helpful to me:
Started because I wanted to be able to think in cm, rather than a indefinite mix of cm, inches, and feet, and "measure with my eye" reasonably accurately. Expected sideeffect of better ability to draw and space objects in perspective
Basically: Get tape measure. Guess all the important dimensions of something, check the actual measurements, calculate the degree of error. Repeat. Aiming for <15% error in all dimensions, and selecting objects with a wide range of dimensions.
Was very effective. Currently using the length of my palm as my main unit (9cm) -- cause it's easy to imagine putting my hand on something and then alternating hands to measure out the dimensions. Probably need a few additional standards for smaller or bigger things - 180cm my height, 1.5cm the width of my index finger.
Errata:
* Ignore the 'exponential measurement' comment; I wasn't able to make that work.
