Aviary has come a long way from its humble origins as a Flickr plugin -- over the last year it's graduated to a standalone app, been given a makeover and has even been ported to Windows 8. Today the popular photo-editing software lands on yet another platform: Windows Phone 8. As on iOS and Android, the app itself is free and comes with a bunch of filters and stickers. Extra packs can usually be purchased for two bucks a pop, but WP8 users can get them for free for a limited time -- not bad for a digital lizard sombrero.
