In addition to The Art of Algorithm exhibition [we covered this week](http://killscreendaily.com/articles/art-algorithm-exhibition-aims-make-hidden-systems-viewable/?ref=killscreen.com), another illuminating exhibition is gracing the [London Design Festival](http://www.londondesignfestival.com/?ref=killscreen.com). Product designer [Felix de Pass](http://www.felixdepass.com/?ref=killscreen.com), graphic designer Michael Montgomery, and ceramicist [Ian McIntyre](http://ianmcintyre.co.uk/?ref=killscreen.com), with the blessing of big-faced watch makers Officine Panerai, to create an installation known as *Candela.*

It’s currently resting in the V&A Museum’s Tapestry Gallery and consists of an enormous, spinning wheel dotted with more than 700 LED lights. The greenish hue is due to a material known as [Super-LumiNova](http://en.wikipedia.org/wiki/Super-LumiNova?ref=killscreen.com), the same material the keeps watch faces bright even in the dark. Super-LumiNova is based on LumiNova pigments, which was invented in 1993 by Nemoto & Co., Ltd. of Japan. You’ve likely used it for those tiny stars we put on our ceiling as kids.

Here’s how *Candela* works. The wheel spins the photo-luminisecent surface which passes over the LEDs. Those lights charge the surface and a the glowing green appearance appears as an afterglow. And much like you need to put your watch face in the sun to recharge its glow, *Candela*‘s green appearance changes as it recharges.

*Candela will be [on view until September 21st](http://www.londondesignfestival.com/events/officine-panerai-collaborates-de-pass-montgomery-and-mcintyre?ref=killscreen.com) aka Sunday Sunday Sunday!*
