Aristid is a tool for rendering of L-systems in plane (2D) based on Turtle graphics.
You have the option to set initial rotation, scale, random change of movement, drawing and rotation, color and width of a pen and background color per each L-system. If the system contains more drawing symbols you can set pen color for each one of them. It is also possible to set whether you want the L-system to be rendered at once or from the first point to the last one.
Application comes with pre-installed database of 20 well known L-systems, which can be modified as you wish. You can also add a new one or delete.
