Fontplore is an interactive application designed for searching and exploring font databases.
Fontplore helps you to easily find the right typeface for your project in a collection of several thousands of fonts. It lets you browse, preview, compare and print the fonts you are interested in.
And the clou is: It does all that on an interactive table, using tangible objects to navigate and control actions, so the workflow is easy to understand - easy to grasp!
