LilyView is a lightweight, Mutli-Touch friendly image viewer that’s handy and doesn’t get in your way.

Lightweight. There’s no image library to load, you just browse images in a folder.
• Chromeless. No controls are visible until they are really necessary.
• Multi-Touch friendly. You can literally touch the image when using a trackpad, but LilyView works just fine with keyboard and mouse.

As a bonus:
• Create ambient lighting effect in your room during a slide show by connecting Philips Hue color bulbs or Lightpack luminaries. Colors of the lights will match the currently viewed image.
• Use hand gestures in the air to control the images (swipe, rotate, zoom) by connecting LeapMotion hand gesture controller.

What's New in Version 1.2
