Artisteer is a tool that lets you make Websites and themes for WordPress, Joomla and Blogger without any programming. You just have to choose the platform of your theme, Navigate through each tab containing various options and customize them. Artisteer has a special feature called ‘Suggest Idea’ under the ‘ideas’ taband If you click on the button it generates a ready made theme for customization , You can then modify the theme with your own liking. One of the coolest thing i like about Artisteer is that you can even add flash animations to the header of your theme without designing in Flash Professional. They have a wide collection of Wallpapers, Animations, Fonts, Header Options and so on… Artisteer is painless and easy to use for everyone. You can customize everything that’s on the theme. They have a trial version that you can try it and then purchase it. Both Mac and Windows clients are available. Here’s a small video demonstration on Artisteer.
Don’t forget that Artisteer is not the only tool for making themes for WordPress, Lubith is also an alternative but it’s works online and even easier.
