I figured out how it was done. There is a variable that sets the number of axes for the grid. Normally you can set it to 2 or 3 in the Grid configuration setting (double click on the grid for options), but you can also set it to whatever number you want in the console. By setting the number of grid axes to some large value (6 or 8 for example), you will get a very strange looking (and somewhat beautiful) grid pattern!
litz - Bellow the box where you enter your comments you should see two rows of smiley faces. Simply set your cursor where you want the smiley to show and then click on the desired smiley. If you do not see two rows of smiley's then there may be something wrong with how your browser is configured. It may be rejecting smileys for some reason.
