In response to this morning’s post about self-captioning POV ping pong paddles, a helpful commenter pointed me at this “action POV” gimmick from Flickr user zeni666. There’s not much detail, other than that it involves an Arduino and 7 white LEDs. But POV displays are old hat, around here. Check the “More” block for all kinds of how-to. [Thanks, 23N!]
Inspired by 19th Century Standhopes, Bristol artist Luke Jerram (of “Play me, I’m yours” fame) designed this elegant and inspired portrait projecting ring for is wife Shelina Nanji as a wedding ring. Working together with jeweler Tamrakar, Jerram created a ring that, in a darkened room, with a light source behind it, will project a series of portraits from a selection of miniature slides.
As a compliment to this morning’s post about making “light orbs,” here’s a second Flickr tutorial, from user tdub303, about making and using “light stencils” in your long-exposure light photography. Basically, the stencil is cut out of a light-tight box holding a camera flash, which is fired off to illuminate the design and record it on the exposure.
Original, beautiful, simple. Easy to remake. From designer Sarah Dayo. She calls it “Glimpse.” Reported dimensions are 77×36″. [via NOTCOT[]
This is the PT54 PhlatLight from Luminus Devices, Inc. It’s intended for use in portable video projectors. More photos of the setup here. [via Hacked Gadgets]
This tree is from an analysis of small subunit rRNA sequences sampled
from about 3,000 species from throughout the Tree of Life. The species were chosen based on their availability, but we attempted to include most of the major groups, sampled
very roughly in proportion to the number of known species in each group (although many
groups remain over- or under-represented). The number of species represented is approximately the square-root of the number of species thought to exist on Earth
(i.e., three thousand out of an estimated nine million species), or about 0.18% of the 1.7 million species that have been formally described and named.
Sci-fi and horror author extraordinaire, John Shirley (whom William Gibson dubbed “Cyberpunk Patient Zero”), sent me a link to this fascinating article about the birth of the square pixel in digital imaging. The piece starts out: Russell Kirsch says he’s sorry. More than 50 years ago, Kirsch took a picture of his infant son and […]
