A text editor for maths. Simple algebra should be faster and more intuitive to perform on a computer than on paper and should look like maths. Write small fragments in plain text; perform simple click-and-drag algebra with the mouse; and explore more involved algebra through keyboard shortcuts. When done, save as plain text files or export to LaTeX and HTML.
Perceptron is a video feedback engine with a variety of extraordinary graphical effects. Perceptron is an endless flow of transforming visuals.
