Have a look on Flickr, there are loads of people doing these. The key is to finding something a little bit original. I would say find a theme and go from there. I quite like the one of some dude who has taken the shot on Oxford Street with his Stormie holding a 'Golf Sale' sign.
eBay was my only source as any other place either have them at ridiculous £££ or they don't sell them individually. Mind you, many eBay sellers are selling them at £4+ each! I got mine for about £2.50 each - I'm still considering more... 9 of them can't make a big enough armyNice set of photos, I wouldn't call them macro though because they don't show anything your eye can't make out anyway.
Btw, where can I get some too?
Dude, what are you shooting with? I thought you sold all your gear?
The pics are ace. I've been looking for similar "toys" to play with, as I love how you can capture the illusion of emotion in them.
...and I now have some. Although I still really don't know why! Damn you!
Mr Jones I can't see your pics on this poxy phone so I look forward to looking at them when I can get on the computer later!
