This is a clip of Sanrio characters interacting across two 3D billboards outside of Shinjuku Station in Tokyo. Is this the best use of 3D display technology? There’s no question, and I don’t expect to see anything more impressive until 4D billboards, which, let’s not kid ourselves, Japan probably already

This is a worthwhile (and trippy) stop-motion animation created by animator Daren Jannace using the 10,946 Post-It notes he drew over the course of a year (30 a day x 365, minus 4 for some reason). The soundtrack is audio taken from his phone during the year of animation. Played

This is a video of Japanese guitarist/composer/producer Masayoshi Takanaka performing jazz pianist Mal Waldron’s ‘Left Alone’ on a guitar that has a functional model train running around it. How about that! The train only goes around the outside of the body then stops and reverses though, it doesn’t actually cross

In the event you manage to get one of your lowly pawns all the way across the board in a game of chess, you have to promote it to another piece so it can continue to battle. Most commonly chosen is the queen on account of her maneuverability. And this

This is the Kinetic LED Display Wall developed by JYVisions of Shenzhen, China. In addition to all the programmable LEDs, each block can also move outward from the wall for extra visual effect. Hey — anything to get people’s attention. It’s nearly impossible to get people to look up from

This is a video from Youtuber Half-Asleep Chris (just imagine what he could accomplish with a pot of coffee), who built an amusement park river ride in his backyard for a LEGO boat. In his own words: “It goes through caves, crystal grottos, temples, and more, inspired by the likes

This is a video of Rube Goldberg machinist Joseph Herscher (previously) demonstrating his Ultimate Snooze Machine 2.0, a machine that repeatedly smacks and whacks a Casetify protected iPhone on its way to getting Joseph out of bed. The machine itself is beautifully crafted, and works flawlessly. I wonder how many

Constructed by HackADay user mircemk using as many 3D printed parts as possible, this self-balancing cube uses an Arduino Nano microcontroller and MPU6050 gyroscope / accelerometer to control 3 motor-driven reaction wheels to keep itself balanced — even standing on one corner on a slope! Me? I can’t stand on
