a blur of hands

This is a blur of hands from a group of peopel with learning disabilities that I work with. They are working on some new dance routines at the moment . They call themselves KAT and they are KOOL.
If you do a search on youtube for Lachies lunch you will see an amaziing gentle video that one of them made. Leaving a rating and a comment will encourage them all.
I have just realised what the little squares at the bottom left are for. Tried to rate Jens last pic by clicking on a square but nothing happened. Help - What do I do?
I am going to print some of my blip pix and just leave them in the places that I took them. No idea why. Just thought I would.
