We are all familiar with virtual and augmented realities, but there is also an inner reality which we have been exploring for thousands of years. Paleolithic rock art dating as far back as 30,000 years depicts simple geometric patterns that are referred to as entopic (“within the eye”) imagery. The patterns typically take the form of lattice formations (honeycomb, checkerboard and triangles), tunnels and spirals. We do not know the what specific parts of our vision system is responsible for generating the patterns, but we have found many ways to trigger them.
Entopic images can be generated through a variety of techniques.
Homo sapiens and possibly even neanderthals have been hard wired to produce these visual patterns. Comparing the entopic imagery from the first two columns above with the San Rock Art and Paleolithic Art shows a number of matching patterns. Similar examples of these geometric patterns have been found in other parts of Africa, Europe, Asia and North America.
After the initial basic patterns are observed things progress to compounded imagery. A common experience is for a stage 3 image to form which is typically a tunnel that is pulsing and rotating slowly in two directions. On the edges of the tunnel there are small squares shaped liked tiny televisions. The structure resembles a black hole. This vortex has been associated with near-death and shamanic psychedelic experiences. Shamans typically speak of entering the other world through a hole in the ground. This level of imagery is often associated with powerful emotions.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
