Have just come across
Sir Benfro from
Paul Smith. It's a up and coming interactive site for children, not much there yet - but Dappler has me hooked.
I cannot link you directly to the page, but if you go to
sirbenfro.com, click on "i am small" and either watch the introductory flash, or bypass it by clicking "Main Menu", then use the flying cloud called "Dappler" where you will find a musical game of bouncing balls on a series of instruments. The convoluted paths one can produce reminds me of
Whizzball.
Hours of fun for when you really should have better things to do.
