Have an enchanting experience and re-discover a classic masterpiece. ::::: REVIEWS ::::: "Very cool! An interactive animation of van Gogh's 'The Starry Night'." MoMA - The Museum of Modern Art of New York (facebook page) "Imagine being Vincent Van Gogh. Imagine giving form to 'Starry Night' with your hands. ... Playing the artist instead of the observer is now possible. ... As the viewer drags his finger across the painting, the dashed oil lines react, creating a river-like effect of blues and golds over the night sky. With each brushstroke movement, a soft note of ambient music rings out as well. The work that went into creating such an elaborate piece of art is impressive. Vrellis took a piece with a seemingly unsurpassable amount of artistic merit, and breathed new life into it." Huffington Post "We find Vrellis' interactive piece enchanting - and even, given Van Gogh's tragic story, emotionally powerful." C|NET "Van Gogh's Starry Night modded into beautiful interactive light and sound show. …This is one of those little projects you wish you could just play with the second you've seen it." Engadget "The effect is so beautiful and mesmerising." Gizmodo "Beauty through simplicity at its finest and most playful." Creative Applications Network "A very fascinating version of ‘Starry Night’... The result is stunning!" Today and tomorrow "This interactive version of Van Gogh’s Starry Night seems to be something wholly different and wonderful.” Colossal art & design "The work finds success in subtlety.” Design.org "Designer Petros Vrellis adds a whole new dimension with his animated and interactive version of the painting." Dutch daily news "The results, which also have a musical soundtrack, are quite stunning." The verge "This app can function as a lovely example of new possibilities. It's so impressive, allowing everyone to feel like Van Gogh for a few moments." O Globo "If Vincent had the tools that we have today, this is the work that he would have created." skyguide.newsvine.com "Utterly beautiful to look at and interact with ... positively delightful, both peaceful and wondrous with a similarly attractive musical score. ... Using a finger to ripple through the artwork is a mesmerising experience. ... It makes art accessible for the masses and brings it to life for children." 148Apps.com "With hypnotic relaxing visuals and audio, 'Starry Night’ is our new favorite thing to play with on a rainy Sunday afternoon. ... It is hard to describe what a wonderfully immersive experience it is getting hands-on with an art piece like this, you just have to have a go." iPadCreative.com ::::: INSTRUCTIONS ::::: - There are three modes: interaction, navigation, screen-saver and dream mode. 1. In interaction mode, just touch to interact with the brushstrokes! 2. In navigation mode, use one finger to rotate around a point, two fingers to zoom and pan. 3. In screen-saver mode, just relax and watch the animation with automated smooth camera movements; you can also touch the brushstrokes! 4. In dream mode, see the original painting melt into a colorful dreamscape. ::::: FEATURES ::::: - Enchanting animation - Immersive 3D zoom and pan - Dynamic interaction - Speed selection - Responsive background music ::::: PREVIEW ::::: This app is an modern interpretation of this video: https://www.youtube.com/watch?v=pCHFAsXYHGA ::::: TIP ::::: For best iPad experience, disable "Multitasking Gestures". ::::: SUPPORT ::::: For any problems please email us at: info@artof01.com
