|
||
Gosper. Many convergent lines are drawn on a color monitor in such a way
|
||
that every pixel struck has its color incremented. The lines all have one
|
||
endpoint in the middle of the screen; the other endpoints are spaced one
|
||
pixel apart around the perimeter of a large square. The color map is then
|
||
repeatedly rotated. This results in a striking, rainbow-hued, shimmering
|
||
four-leaf clover. Gosper joked about keeping it hidden from the FDA (the
|
||
U.S.'s Food and Drug Administration) lest its hallucinogenic properties
|
||
cause it to be banned.</p></dd><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="smoke-test.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="../S.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="smoot.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">smoke test </td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"> smoot</td></tr></table></div></body></html>
