This piece by Mathieu Lehanneur is incredible! From designboom:
during its international gardens festival — on from now until november 2016 — french designer mathieu lehanneur brings a ‘liquid marble’ installation to the courtyard of domaine de chaumont-sur-loire centre d’arts et de nature in france. ‘petite loire’ highlights the ways in which marble, water and light come together to evoke a dynamic feeling of a river in motion. comprising a single piece of hand-polished green marble designed using 3D software, the surreal object reproduces the effect of wind passing over the surface of water, transforming an ephemeral moment into something solid. ‘petite loire’ — a continuation of lehanneur’s ‘liquid marble’ series — explores the potential of using algorithms to manifest a transitory moment in time.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
