Yes, but no, I don't want any globals.

No that's correct. Init-variables sets the value of all the variables which are dependent upon the value of cellsize. When the board is resized, it is called again - in the resize-board function which you call 'do-something.

Haha. From what I read, it was just a matter of wrapping my procedural code into a separate context :)

Yes, I agree.
