Formula: Iterations: Making iterations too large makes to drawing time extremely big and may freeze your web browser.

Instructions: In the formula f is a line, + rotates right, - rotates left, * rotates forward, / rotates backward, [ saves position, ] reverts to previous point. If more than one iteration is used then f is replaced by the whole instruction e.g. 2 iterations of f+f is (f+f)+(f+f) brackets are used here for clarity, they do not have any effect. As you can see the number of lines increases exponentially as the number of iterations increases.

Controls: Up arrow-move up, Down arrow-move down, Left arrow-move left, Right arrow-move right, Page Up-move forward, Page Down-move backward
S/W-spin left/right, E/D-roll, Q/A - rotate down/up Note that rotating is some directions may rotate th other rotational axes so unexpected effects may occur.
