LIGHTS & MAGIC.  First, choose the size and distance, then draw with your fingers or by moving the phone itself: put your finger on the screen and use your hand instead. Or you could do both!  You can cancel or manage your free trial's auto-renewal in your Account Settings after purchase.  Choose from many 3D background environments: beautiful sunsets, night skies, Earth's orbit, outer space in a faraway galaxy, and many more! 3D BRUSHES.  Write something in the air around you or put a snake next to someone's feet, draw a wall from medieval bricks or add some mustard to your favorite dish! FIREWORKS.  Explore dozens of live, bright, colorful effects, like neon, glow, smoke, sparkles, and all other sorts of magic.  Volumetric photorealistic brushes with lots of unique materials: metal, plastic, gems, rock, wood, marble, organic, and others.  If you run into trouble with positioning, for instance, when your drawings jitter or fly away, it's most probable that you haven't calibrated your phone good enough first.  Write a note with a sparkler firework, fill the air with fireflies, or light up the night with aurora lights!  When calibrating, try moving the phone smoothly and in different directions, so as to let the app better learn the space around you.  Bring a festive atmosphere anywhere you are, and make your videos shine and pop! EXPLOSIONS.  Ultrarealistic, Hollywood-quality 3D explosions to make truly breathtaking videos.  Colorful fireworks made from thousands of particles!
