You're all just jealous of my jetpack

I had a good rant the other day about science fiction and generic boundaries. I'm not going to reopen that debate - but it reminded me of two lovely Tom Gauld cartoons from the Guardian. I tried to buy the first one, but someone else had snapped it up. I did get hold of the second one though: it hangs in my office, next to the 'Horrid Children in Literature' strip.
