is inspired by the conflicting orientation cues that are used throughout the artwork of M.C. Escher. The technique of projecting selected faces from
hypercubes is adapted from deBruijn’s method for quasiperiodic tilings, which is illustrated in the deBruijn applet.
- Click to increase n, SHIFT-click to reduce n, CTRL-click to get a new random tiling with the same n.
- You can display this applet in a large window (suitable for taking screen shots to use as desktop wallpaper) by hitting the W key.
You might have to select the applet first by clicking on it (you can use SHIFT-CTRL-click to select the applet without changing the tiling).
- To close the large window, you can use the close gadget on its frame (if there is one), or hit either the C key or the ESC key.
Some browsers, alas, will not pass any keystrokes to the large window, even after you’ve clicked on it, so as an EMERGENCY EXIT you can RIGHT-click the mouse to close the large window.
- Hitting the SPACE BAR will cause the applet to stop/start automatically scrolling across the tiling.
Hitting the PAGE UP and PAGE DOWN keys scrolls a full page;
the UP ARROW and DOWN ARROW keys scroll by one tenth of a page.
- Some browsers have a bug that will cause the applet to ignore these key commands after you’ve opened a large window then closed it.
If you find the applet ignoring these commands, even after you click on it, you will probably need to reload the page.
