WC strobe
I promised geek revelry, and that’s what you’re getting. I came across this idea at Daan‘s birthday party, and it deserves spreading to the other hemisphere. It’s very simple: put a strobe light in the WC, and turn off the ordinary light.
Why would you want to do such a thing? Blokes, try it and you’ll be amazed. Ladies, I presume you can get much the same effect from a running tap, with a little fine-tuning, but you’re going to miss out on the personal involvement factor. Sorry, there’s nothing we can do about that, short of radical surgery.
Geeky? Yes. Tacky? Yes. Delightfully amusing? Absolutely.
