This is what I was thinking[0]. There are loads of really expressive BSL signs that are more than appropriate for this kind of discussion. This is unsurprising as deaf people have group conversations too! As a note for those without experience of BSL, the signs are often dynamic and where consensus/voting is being expressed you usually hold the last part of the sign.

The occupy signs are deliberately chosen to be readable from really great distances and not being part of a larger signing system they are hard to expand upon.

What an oddly helpful but unhelpful site.

Hiding the symbols behind videos means I can't see what the symbol is as the people haven't made it yet, unless I play the video.

Couldn't they have at least one sketch or marked up jpeg showing the symbol or gesture?

Weird.

It's made completely by contributors in their own time.

It's also much harder to create a sketch than simply record yourself signing.

And sketched signs are pretty much useless for everything except finger spelling
