According to the homepage of the Genius Math Tool, “Genius is a calculator program similiar in some aspects to BC, Matlab or Maple. GEL is the name of its extention language (stands for “Genius Extension Language”, clever huh?), in fact, a large part of the standard genius functions are written in GEL itself.”

The developer says that after seven and a half years of developement (which includes seven years Genius just sort of sat and wasn’t developed much at all) it can finally do 3D surfaces and print. This is an amazing little app for those of you with a mathmatical bent. And of course Genius is free software, released under the GNU General Public License.
