From Spencer Boerup:

For photographers, attaching a flash modifier is a chore. Either you need a special mount designed just your flash, or you have to use velcro, elastic, or a whole slew of other materials just to get your modifiers to stay in place. So six months ago I developed Magmod, the best flash modifier system ever.

Magmod is a magnetic system of mounting flash modifiers that works with almost any strobe. Using extremely strong magnets, the modifiers instantly lock into place, without fiddling with straps or adjustments. You can add as many modifiers as you want, simply stacking one on top of the other. Now photographers can create custom light patterns with less gear and in far less time than before.

We launched Magmod on Kickstarter two weeks ago, blowing past our funding goal of $35,000 in just a few hours. So far we've raised $153,000.
