Is there such a thing as foot inflation?

[mr small]

After reading this thread I reached deep into my memory banks and remembered seeing something along the lines of foot inflation. So, going through my well organized extrenal hardrive full of 8 years worth of process related stuff I found this pic. Apparently it's from 2001 by an artist named "Big Horse". Not exactly my cup of tea but it was floating around in my subconscious.
