real plane fractals
Patrick J. Naughton.
1991
History Changes in xlockmore distribution
01-Nov-2000: Allocation checks
24-Jun-1997: EJK and RR functions stolen from xmartin2.2
Ed Kubaitis ejk functions and xmartin
Renaldo Recuerdo rr function, generalized exponent version
of the Barry Martin's square root function
10-May-1997: Compatible with xscreensaver
27-Jul-1995: added Peter de Jong's hop from Scientific American
July 87 p. 111. Sometimes they are amazing but there are a
few duds (I did not see a pattern in the parameters).
29-Mar-1995: changed name from hopalong to hop
09-Dec-1994: added Barry Martin's sine hop
Changes in original xlock
29-Oct-1990: fix bad (int) cast.
29-Jul-1990: support for multiple screens.
08-Jul-1990: new timing and colors and new algorithm for fractals.
15-Dec-1989: Fix for proper skipping of {White,Black}Pixel() in colors.
08-Oct-1989: Fixed long standing typo bug in RandomInitHop();
Fixed bug in memory allocation in init_hop();
Moved seconds() to an extern.
Got rid of the % mod since .mod is slow on a sparc.
20-Sep-1989: Lint.
31-Aug-1988: Forked from xlock.c for modularity.
23-Mar-1988: Coded HOPALONG routines from Scientific American Sept. 86 p. 14.
Hopalong was attributed to Barry Martin of Aston University
