‘Rebound’ is a maddeningly simple physics game
Sometimes the simplest games are the most difficult. That’s certainly the case in Rebound, a game in which the only goal is to get a pole as far to the right as possible, but where actually getting very far is incredibly challenging.
NASA has just released this cute chart depicting the various distances traveled by wheeled machines on other worlds.
Space has never been so adorable.
Isotope Titanium Lume Ring
The Isotope is all about contrast. The brilliant glow of the lume, and the sharp lines of the titanium create a visual moment that refuses to be ignored.
The special lume material in the Isotope ring soaks up both natural and artificial light and will glow bright green as soon as it is in a low-light environment. Wear it to bed and it will still be glowing when you get up for that 3am visit to the bathroom!
Moonglow Material:
Moonglow is a ultra-high output photoluminesent polycarbonate. It soaks up both natural and artificial light and will glow bright green for hours once it is in a low-light environment. It also a passive-lume material, meaning it absorbs light. It does not generate its own light as radioactive materials such as tritium do.

AAAHHHHHHHH
The problem of space junk or space debris is increasing. And with out greater dependence on satellites is a grave problem.
There’s a lot of debris floating around in space, and researchers at the Lawrence Livermore National Lab are using supercomputers, optical sensors and other technology to track even small objects that could damage important satellites.
John Henderson, a space scientist at LLNL, explains:
“Everybody uses GPS to get from here to there. We have satellite television, we have weather reports, farmers use satellite data for monitoring crops. If you have a piece of satellite debris whacking into a satellite, in the worst case you now lose that capability. In February of 2009, that actually happened where there was an Iridium communications satellite that collided with a dead Russian Kosmos satellite and so that basically took out a $100 million dollar satellite.
There’s somewhere between 100,000 to 200,000 pieces of debris that we would like to be tracking. And so the supercomputing capabilities that we have here at Livermore are one way to keep track of that.”
Laser Cut Record
Instructables project from Amanda Ghassaei that can allow you to create playable records with a laser cutter (sure the sound isn’t that great, but still …) - video embedded below:
A few months back, I wrote about how I used a 3D printer to transform any mp3 into a physical record. Though all the documentation for that project is available here, and the 3D models could potentially be printed through an online fabrication service, I knew that the barrier to entry for normal people interested in trying out the process themselves was prohibitively high. With this project I wanted to try to extend the idea of digitally fabricated records to use relatively common and affordable machines and materials so that (hopefully) more people can participate, experiment, and actually use all this documentation I’ve been writing.
