At some stage in the not too distant future, astronauts will pay a visit to Mars. I would like one of them to wear a set of my 'Footprints on Mars' overshoes and walk around in a perfectly marked out circle.

The overshoes are actually attachments that clip unto the soles of one of the astronaut's boots, and are designed to leave the perfect imprint of a naked human foot in an area with a suitably soft surface. Once the circle is complete, the surrounding environment would need to be cleaned up to isolate the circle of steps.

I'm sure NASA, or whomever, will easily say no, but that's why we have the halfbakery!

Better yet - make 'em camel hoofprints, and don't tell anyone.

Even better yetter - use shoes with a 3-D adjustable tread pattern.

Start on the edge of a dried up river bed, with lobe- fin footprints. Over the next few tens of metres, transition smoothly through webbed feet, clawed lizardy toes, giant shrews, opposable-toed feet, human footprints and, finally, pogo-stick dimples just to make future visitors wonder.

Have you any idea how hard it is to get rid of unwanted bacteria-infested water?

Include some knee marks, hand prints and it still might be too advanced.
