Ridge? Good grief [Roll Eyes]

You may call me Dick or Tricky if it's easier, just don't call me late for dinner.

I know imaginary numbers are useful, I'm on a wind-up. Just wanted to point out that far from being a math geek I'm more of a math numpty.

Translations and rotations using matrices make my head hurt.

My math tends towards the more practical - "I have £20 in my pocket. If I get a curry on the way home, how many pints of beer can I afford first?"
