This gizmo is basically a LED light fixture that attaches to your showerhead. Its purpose: It changes colour according to the temperature of the water, and looks pretty funky in the dark. It costs about 100 dollars, so it doesn’t come cheap, and it is only avaliable overseas.
Apologies for advertising something you can’t even get here. But, hopefully some SA entrepreneur will read this article, design a better one, charge half the price, and give me a share of the profits. *Hint Hint*
