Marblescape
Read full descriptionHide full description
A wooden marble run that builds itself and goes on forever. Marblescape is an app for simply watching it roll. Dominoes, seesaws, a xylophone, a loop-the-loop: 21 gadgets link up at random, right before your eyes. A striped marble rolls, bounces and spins its way through, and the camera follows quietly behind. It isn’t a video on repeat. Your device draws every moment live, in real time. OPEN IT, AND IT’S ALREADY ROLLING • Behind the title screen, the marble is already on its way. Tap Start and the buttons slip away, leaving just the marble run. • It moves like the real thing: faster downhill, riding up the outside of curves, bouncing down steps. • New gadgets keep appearing ahead, so there’s always something about to happen. • Every launch builds a different course. 21 GADGETS On the way down: Switchbacks, Helix, Bouncy Stairs, Xylophone, Pin Board, Flip Ladder, Dominoes, Log Roll, Ball Row, Hammer, Spiral Funnel, Seesaw, Trapeze, Hoop Jump, Wave Rail, Halfpipe and Loop-the-Loop. Carrying the marble back up: Elevator, Spring Launcher, Screw Lift and Domino Staircase. WATCH IT YOUR WAY • Spread two fingers to move in, and the marble comes to the center. Pinch to pull back and take in the whole run. • Drag to swing around the run, or look straight down from above. • Double-tap to return to the usual view. • Tilt the device and the camera drifts around a little, then settles back on its own. • Tap once for a small Back button. LEAVE IT RUNNING • Lay a digital clock over the run: six typefaces, with any size, opacity and position. The date is written the way your region writes it. • Turn on Keep screen on, and the screen won’t lock while you watch. • When your device warms up or Low Power Mode is on, Marblescape lowers the resolution slightly to keep things smooth. AFTER DARK (EXPERIMENTAL) Choose Night under Appearance in Settings. The world turns deep blue under the moon, lanterns beside the rails light the course with a soft, candle-like flicker, and dust in the air catches the light now and then. The same gadgets, with a whole new mood. WHERE IT FITS • For kids who love marble runs: a toy that never needs rebuilding. • On a desk or a bedside table: something calm, moving quietly at the edge of your vision. • At bedtime: dim the lights and let the night scene play quietly. • For fans of gadgets and contraptions: a little world of physics in the palm of your hand. FOR EVERY SCREEN Built natively for iPhone, iPad and iPhone Duo, in portrait and landscape. On iPhone Duo, the run fills the outer screen when closed and the large inner screen when open, with the buttons kept clear of the fold. FREE. TIPS WELCOME Every gadget and every setting is free. No ads, no account, no data collected. If you enjoy it, you can leave the developer a tip from Settings. Making videos? Marblescape Pro, the same marble run for Final Cut Pro and Motion, is coming soon. More: https://www.gyuniku.jp/apps/marblescape.php
