I am so happy you decided to try out Aviary! Aviary represents the future of creation: a place where you can collaborate with other artists of all different skill levels to create incredible works. If only Michaelangelo and Picasso had Internet access as well...- avi

I discovered a link to this website today and found it pretty cool. For anyone interested in graphics design, it's like an online Adobe suite you can use right inside of your browser! It's Flash and JavaScript and maybe Ajax combined, so it can do some amazing things for a browser application. Once you register an account, you can save all of the files you create to a profile that other users can view. Also, if you want to, you can let other people import your work and make deviations of it, which can be pretty fun. Or you could have multiple people doing different parts of an image, like one draws, someone else colors, etc. From the description, you're probably thinking it's low quality stuff, but noooooooo. This was well made, check out for yourself.

Aviary has:
Raven - a vector editor
Phoenix - an image editor (it's like Photoshop without the plugins and price tag)
Peacock - an add-on for creating filters and mind blowing effects
Toucan - It even has a color scheme generator!

Total cost: Free.

Yeah, you read that right. This service and all of its professional quality web suite is free for you to use without even running an installer (unless you're back in the 56k age and you don't have the Flash plug-in...)

Now I've experienced drawing and vector applications in Flash before, and I can tell you that it can get laggy FAST. BUT I did not experience any lag with these tools. They ran just as they would in a win32 application. The only downside I could see was that it doesn't quite work right in Opera due to layout problems(?). It works fine in Firefox and I imagine IE though. Oh and editing pixel by pixel doesn't seem possible, unless there is some work around I am unaware of. Anyway, I don't mean to be an advert-whore but this stuff is just too cool! Never would I have imagined Flash being capable of emulating Photoshop without lacking... almost everything.

There are a couple of restrictions that require an upgraded account, but that's mostly just for privacy settings.

I imported and made this with Phoenix lawl.
