Scrollable, multiple selection checkboxes

Via Bim Egan of the RNIB, and passed on to me by my colleague, Sonia Carter, is this nice little accessible solution to multiple checkbox selections and saving space (i.e. "making it look good") at the same time.

This was, as pointed out by Bim, discussed on the webaim discussion board a while ago - to be honest, I was stuck back in the days of thinking that CTRL+ multiple option selection was fine for the "select" element. But, care of Bim is this neat solution on C82: "check it, don't select it". I really like this - neat and easy to code.
