Interest in risps has happily spawned pages, videos and links elsewhere on the Net.
The Association of Teachers of Mathematics has supported the risps project warmly.
Each issue of Mathematics Teaching currently carries a risp.
We have worked together to film some risp material which is available on Youtube.
