Easing Generator is custom easing function editor for ActionScript tween engine. You can set original easing to tween transition parameter. Interface looks like Flash Professional CS5, but this is AIR App. So, you can get free.
My service named Icon Generator is renewaled. You can generate icon like as Adobe Creative Suite 5, very easily. And of course when you save it the application uses the file APIs to write 6 different sizes of the icon for you. This servise build with Flex Framework 4.
But, I am also developer of Icon Generator which is known as very simple application for web designer. This has result of over 27,000 downloads and top 7 at most popular ranking in Adobe Marketplace (19th May, 2009).
I made demo movie which introduce how to install and use. It’s very very simple. Enjoy.
