Please email me if you’d like to be placed on the waiting list for a second series of these to be released sometime in the next several years. Thanks!

Microetched prints are machine replicated, aluminized PET film sealed between two sheets of glass.

Note: There are 22K gold microetchings of this etching available as well as the usual fine art prints.


To get the full effect of what the microetched print looks like, please watch the video above. 

This piece is an ode to one of the most iconic regions in neuroanatomy, and one of the regions which best defines our individuality and humanity. Brainbow Hippocampus depicts the actively firing anatomy and complex circuitry of the hippocampus, the hub of learning, memory, and integration of experience in the brain. The reflective animations highlight the classic trisynaptic circuitry between the perforant path, granule cells of CA3, Schaffer collaterals to CA1, and then the output to the entorhinal cortex and subiculum.

When lit with multicolored lamps, the Brainbow Hippocampus microetching also illustrates the brainbow genetic technique wherein scientists splice in multicolored fluorescent proteins into every neuron in the brain in order to make the identification and mapping of neurons easier. Similar to this technique, a few different colors of light can mix onto the etching in many different ways and can produce a spectacular variety of colors. As the color of the etching is entirely dependent on the lighting, literally thousands of multicolored palettes are possible.

Microetched prints are 22″ X 30″, machine replicated and aluminized films sealed between sheets of glass to preserve them for many years to come. They come with a certificate of authenticy. They feature the same dramatic reflective effects as original gold etchings (gold etchings for Brainbow Hippocampus can be found here), but they are machine replicated and finished with aluminum instead of gold to be able to offer them at a more accessible price point. Lighting is not included in the price, but I will certainly advise on the best ways to achieve it. I highly recommend track lighting with color programmable RGB bulbs to illuminate Brainbow Hippocampus as it is the simplest and most flexible lighting system and is capable of the most dramatic visual effects. All shots taken in the video where the camera is moving were made using a track lighting system. You can read more about how to illuminate microetchings in this document here.

Manufacturing of microetched prints is a complex multistep process and many of my suppliers are behind in their work this year, thus they are not expected to ship until mid to late December, 2020.

Microetched print lit with several different lighting schemes:

International Shipping information:

Please note – I can now ship framed microetched prints overseas. The cost varies depending on the country and can be as little as $150 to Canada or as much as $350 or so to Australia. Please allow 4-8 weeks for shipment to arrive The website does not accurately calculate international shipping on these, so if you order from abroad I will need to calculate the exact shipping cost and bill you separately for it.

Shipping from Philadephia, PA
Shipping framed microetched prints within the U.S. – $95 flat rate. Shipments typically arrive within 3-4 weeks from the date of order.  These microetched prints will not start shipping until likely mid to late-ish December and have a transit time of up to a week for domestic orders.

Additional information on lighting, etc.

Both 22K original microetchings and microetched prints can appear dramatically different depending on how they are lit, and below are a series of still images demonstrating how the piece looks different depending on where the lights are (white light progression image) . You can light it with one white light, with 10 or more colored lights, or with anything in between. Lighting these is very flexible and a track lighting system will give you the most options to work with. Below are some examples of the piece lit with white and blue light, as well as closeups of the imagery and the frame.

The plain black frame pictured above is the standard frame for this piece. For an extra $180 you can request the deluxe frame pictured below. Please email me along with your order if you would like it with the deluxe frame and I can bill you separately for that.

Please read this .pdf for detailed information and product recommendations on how to light your microetching.
