Sunny and cheery icon wanted for iPhone/Android/Mac app!

Morning Sun

Morning Sun is a sunrise alarm or "wake-up light" app for iOs, Android and Mac! Briefly explained, it will wake you up more pleasurable and relaxed by simulating sunrise and playing soothing natural sounds.

People who find it hard to wake up in winter time or are otherwise fed up with their current nasty alarm clock.

First and foremost, the icon is needed for ALL three platforms: iOs(iphone etc), Android and Mac. You don't have to create unique icons for each, but use the same design across all three and adjust to each guideline.

Android Launcher icon guidelines: http://developer.android.com/guide/…esign.html

Mac icon guidelines: http://developer.apple.com/library/…Icons.html

Some thoughts:
- the icon should have a positive "vibe" in it; soothing warm colours, soft graphics etc.
- Sunrise is quite obvious choice, but I have seen it used frequently in similar apps as such. If you somehow could picture the perfect sunny summer morning to wake up!
- Remember simple enough, so it wont get cluttered with info! Let your imagination flow, but keep it professional :)
- prefer vector format

Required sizes:
iOs: 512x512, 114x114, 72x72, 57x57
Android: 36x36, 48x48, 72x72
Mac: 512x512, 128x128, 32x32, 16x16

I hope to get the PNG files, AI and/or layered PSD file.

Please do not use any stock images or clip art that I have to purchase to use!
