learning breakthrough

[Mousie]

anyone heard of this? something about a ball bouncing against a board - meant to be amazing in the right circumstances. haven't described this very well....

have been internet trawling and friend trawling for advice for my troubled dd - and someone told me about this thing - from america - basically exercises for a child to do twice a day, involving throwing a ball at somesort of grid - was just hoping someone had heard of it and could endorse or not either way. i think i just googled "learning breakthrough" and found a site but it's a lot of money for a shot in the dark...
