FLTK (pronounced "fulltick") is a cross-platform C++ GUI toolkit for UNIX®/Linux® (X11), Microsoft® Windows®, and MacOS® X. FLTK provides modern GUI functionality without the bloat and supports 3D graphics via OpenGL® and its built-in GLUT emulation.

FLTK is designed to be small and modular enough to be statically linked, but works fine as a shared library. FLTK also includes an excellent UI builder called FLUID that can be used to create applications in minutes.

FLTK is provided under the terms of the GNU Library Public License, Version 2 with exceptions that allow for static linking.

The FLTK website was designed with speed in mind. The design as a result is very minimal. Should we change fltk.org? Please write your suggestions into the comments section. (please pick one)
I love the site the way it is
it only needs a different color scheme
it needs a redesign, but minimalistic is good
the FLTK site needs a complete redesign - please hire an artist
