looking at the 'Google earth' thread, the tracks on the blue water look so good, it occured to me - why not start a
"GPS Sea Writing Challenge"like Sky Writing but using the tracks on G/E to spell a name etc.
A bit of a challenge like alpha's.
First to write 'seabreeze' or maybe just 'sea' or 'GPS' or 'Oz' gets a prize (a set of Derwent pencils[}:)][}:)]) or a T-shirt from Lozza

Any photoshop work will be penalised, & any stink-boat or similar shenanigans gets you banned from seabreeze!!!
