Knotswithstanding! is an internet based application built using HTML5, CSS, and JavaScript. It is a pedagogical utility that facilitates the construction and analysis of mathematical knots, as well as the demonstration of knot theory fundamentals. It uses a "stick based" tile layout system, allowing a user to draw a knot by dragging the mouse pointer across a grid. Once a knot is complete, functionality is available to check for validity, identify the number of crossings, and determine other invariants including tricolorability and Dowker notation. It features 500 iterable storage banks, and functionality for a sequence of knot renderings to be "played back" in a style resembling flipbook animation. Playbacks can be edited, reversed, slowed down and sped up.
