ClickThru is a tool to convert static designs into interactive prototypes.
Using ClickThru, you can import interface designs created using your favorite design tool and add interaction layer on top of it. Hence you can convert visually rich designs as well as wireframes into clickable interactive prototypes.
ClickThru provides a method to compose and preview the interaction seamlessly.
Use buttons to mark the hotspots. Add states to show hover effects. Insert Regions to load different user interface modules, in specific areas, in response to button clicks. Use Popups to display popup windows, dialog boxes and menus.
The clickable mockup can be exported as html to share with others.
