"The free Kepler Explorer app for iPhone and iPad allows users to explore some 2,000 planetary systems discovered by NASA's Kepler Mission. The Kepler Mission scans the Milky Way galaxy in search of Earth-size planets in the habitable zones of the stars they orbit."

"Green screen is a cinematographic technique that allows video editors to add a variety of visual effects to their videos. These effects include : adding virtual backgrounds, superimposing subjects over animated backdrops, placing a subject on another shot and many more. Green screen technology has been widely used in weather and movie industry. But now with the emergence of apps such as the ones below, everyone can use this technology to create engaging clips and presentations. As Do Ink explained " Green screen technology is used in the movies to make it look like the actors have landed on an alien planet, and it's used on TV to make it look like your local news announcer is standing in front of an animated weather map. The green screen effect works by combining images from multiple sources into a single video. These images can come from photos or videos in your camera roll, or from the live video camera. ""

"Educational games, or "edutainment," can sometimes be presented as "chocolate-covered broccoli"-that is, learning sugarcoated with fun.  An example is a game that tasks players with reducing fractions to destroy aliens.  Here, the mechanics of play (actions taken in a game) are misaligned with the learning goal. In the past few years, innovative designers smartly began marrying game mechanics to learning goals.  One example is The Land of Venn, in which the mechanic of drawing points, lines, and shapes clearly correlates to the game's goal.  Players draw lines to learn about line"

"With so many Raspberry Pi projects to choose from, it can be tricky to find the one you really want to build. Our advice is to find a way to marry the Pi with something you really love. One great example is TV and movie robots - iconic characters from popular sci-fi that can be rebuild at home with a Raspberry Pi built in. Once constructed, your robot might be able to utter commands when a condition is met (perhaps a sensor detects motion). Or it might move around, learning about its surroundings, or reading information to you from Wikipedia. Whatever you have in mind, it should be relatively straightforward to plan and execute. It may take some time, however. Here are five example projects that show how you can combine a Raspberry Pi 2 or later with your favorite fictional robot. 5 Things Only a Raspberry Pi 2 Can Do 5 Things Only a Raspberry Pi 2 Can Do The latest edition of the pint-sized computer is awesome. So awesome, in fact, that there's 5 things you can only do on a Raspberry Pi 2. READ MORE 1. R2-D2 We've all wanted our very own astromech droid, haven't we? Sure, no one on earth is (currently) operating a light speed drive, but Star Wars droid R2-D2 has far greater abilities than onboard spacecraft maintenance. For instance, he can hold torches, carry a tray of drinks, and launch lightsabers across pits in the desert. Okay, it's unlikely you'll manage to get your own R2-D2 robot to do that… but don't let that put you off. Check out this little guy, controlled by a Raspberry Pi. While this project was based on an existing R2-D2 toy, that shouldn't limit your ambition. You'll find plenty of R2-D2 builds on YouTube. There's a massive R2-D2 building community online. Finding one that has a drive unit should be ideal for integrating a Raspberry Pi (and perhaps an Arduino, which you can use the two together) and developing a more realistic R2-D2 experience.
