These are, I believe, the tubes from which the internet is made. If you journey down inside you will discover that everything is day-glo green and black (take care not to step in the You Tube comments).
I'm a cartoonist and a sculptor. The cartoons are generally aimed at adults and tend to be Not For Everyone. The sculpts are my Feeping Creatures monster figurines and art, and are suitable for all ages. I do a lot of scfi-fi/comic conventions and art fairs where I sell the Feeps as part of my ongoing effort to increase the number of monsters in people's homes and offices.
I come up with the captions for these photos first thing in the morning, when I'm still half asleep. If they seem a little surreal sometimes that's probably why. You are more than welcome to comment with your own caption ideas.
