Fire Wookiee
A from-scratch browser that renders the web content in the style of the opening scroll of a somewhat popular movie franchise. Built in C++ with the graphics rendered in DirectX 10. Current features include tabbed browsing, a spinning deathstar busy indicator, and a basic HTML layout engine.
The font is a 3d model created in Blender. Each character that needs to be display is indexed to a letter in the model and then rendered to the screen.
Home screen.
