Love this - Orange’s Spot the Bull Competition
Thanks to Iain at http://www.crackunit.com/2007/05/22/spot-the-bull/ for reminding me of this. Poke have GPS-enabled a Bull for Orange (at http://spotthebull.orange.co.uk/ and competitors have to guess where it is exactly on a map, to win tickets to Glastonbury.
I really like the combination of web, GPS and a fabulous sense of humour that came up with all of this. Even the Captcha device to beat robot entries is well done. Nice one!
