The first batch of studio's Monkey Brain light arrays for RTI microscopy have shipped to museum

The Monkey Brain is a light array for making reflectance transformation images (RTI) through the microscope. The array incorporates 56 white, high intensity LEDs. With a Lumenera imager, custom software is used to control the lighting sequence and image capture through a single interface.

The project started life as part of the MoMA Thomas Walther collaboration and was used to characterize the surface texture of photographic prints. After a long period of testing and development, we have shipped out two monkey brains to museum labs for further field testing. We anticipate making 5-6 more of these and will then decide whether to "get real," by scaling-up production and outsourcing the manufacturing.

The first monkey brain was made using a whiffle ball cut in half. The shape, the wires, the LEDs (from cell phone cameras) looked something like a monkey brain, especially when covered with goopy electrical insulation (not that anyone on the dev. team has seen an actual monkey brain).

The video shows the underside of the light array, with the LEDs firing in sequence. The video makes the light look oddly yellow / green. Its white (apologies to Kubrikc et al.)
