"NASA's Spacecraft 3D is an augmented reality (AR) application that lets you learn about and interact with a variety of spacecraft that are used to explore our solar system, study Earth, and observe the universe. Using a printed AR Target and the camera on your mobile device, you can get up close with these robotic explorers, see how they move, and learn about the engineering feats used to expand our knowledge and understanding of space. Spacecraft 3D will be updated over time to include more of the amazing spacecraft that act as our robotic eyes on the earth, the solar system and beyond!

"Visualize in real-time the frequencies that you can hear around you and even those you cannot. The SpectrumView analyser provides a high quality real-time spectrogram and spectrum analyser display with configurable sample rate and frequency resolution for the iPhone and iPad. You can use this application to measure the highest tones you can sing, to find the source of an annoying sound, for calibrating musical instruments or generally for all sorts of acoustic analysis.
