Thank you everyone who has emailed, linked to JellyCam, tweeted or blogged. I thought only a few friends of mine were using it, but I guess that's what happens with this groovy internet thing.
A few people have asked about the watermark. My intention was always to have a free version with the watermark and a paid version (for about £5) without it. However with two kids and a brain-draining job I tend to sit zombie-like in front of the tellybox glugging wine instead of getting on with things. (I'm on my second glass now, having just watched 'So you think you can dance?').
Now I know there are a few people outside of my facebook circle who like to dabble in a little JellyCam animation I shall endeavour to turn off the telly more often (I'll stick with the wine though, it helps my coding) and start on the long list of improvements. Top of the list is including a way to add in sound and making a paid version without watermark.
