The small dot in each image (click to enlarge) indicates the location of a hole which will be punched in the card, through which is inserted a red SuperBright LED. The LED is part of a small, self-contained battery unit which is glued to the back of the card. These units are light, water resistant, and invisible from the front of the card. A simple squeeze activates the LED, which blinks blindingly at the observer, allowing peer photolocation in the chambers of the desert night.

The flat lithium batteries support an estimated 200 hours of use, and are replaceable.

The card on the far right was specially distributed to members of the FLESH LAB camp. Designed to look sporty with lab coats, these cards allow access to proprietary Flesh Lab technology, information, brainstates and behavior patterns that could prove hazardous to uncertified personnel. Some space is available for the affixation of a small I.D. photo, as well as the name of the technician to whom the card has been issued.

115 each of the Burning Man designs were made, and 75 Flesh Lab cards, plus 5 or so prototypes each. There are no extras left; they cannot be bought. If you received one at the Black Rock City Arts Festival, it was because you or your art touched my life in some way, an acknowledgement of your effort, at the very least, and quite often of sublime achievement. A few people got 'em from just being in the right place at the right time. Thank you all for being part of my world for this brief, blinking moment.
