Thank you for an array of fine entries. Honourable mentions go to pastille @ 2/32, BBM2 @ 40 (I live quite near Althorp BTW), philip, aristo, Timmo23 (a newbie?), rambler @ 6, and ixion.
The winner passed me by at first - it snuck under the radar and into my affections for its subtle anagram and a neat twist on the 'keeper' motif. The winner is AB's entry:
Frenzied coitus, and he's a keeper...
Congratulations AB, your prize is a neat little device for creating your own chill out music when everything gets too much. Turn down the lights, pour yourself a drink (or maybe do those the other way round) and go to this page, click on a few squares and create your own harmony of the spheres...
