puzzles...
I like puzzles like the next computer literate, amateur maths type guy.
But I felt I was back in school, looking at one of those pointless IQ tests they use to probe us with, when they saw we couldn't be bothered to do the dreary stuff (i.e. non-maths and science), that they (the school) needed to justify their existence (and exam grade rankings).
The first test, was computationally very simple. And just like when I was 8, I skipped to the last problem on the board. I will not reveal what I found because they spoiled the fun, and said they didn't want the answer.
Oh, and I didn't have any glue either.
Carry on...
