				 Cthugha V2.0

		   by the Digital Aasvogel Group. 1993-1994
			    Revision V1.0 - 9Mar94


Who's this Cthugha dude anyway ?

"Cthugha resembles an enormous burning mass continually varying in shape.
It dwells at or near the star Fomalhaut, from whence it may be called.
It is one of the most obscure and remote of all the Great Old Ones."
Call of Cthulhu - Chaosium

When Cthugha is summoned he is always accompanied by Fire Vampires.

'There appeared thousands of tiny points of light. ... The myriad points of
light were living entities of flame!  For wherever they touched, fire sprang
up.'
The dweller in Darkness, by August Derleth



What does this software do then ?

Audio input seeded image processing.
Cool.
Hook up your CD player to the input of your soundblaster card,
or use your CD-ROM player if you've got one.
Run Cthugha V2.0 (DOS program)
Then play some of your coolest music
- and wow, does your screen look like a 90's lava lamp or what ?



Technical Stuff :

Sound Cards :
Only tested with soundblaster Pro and 16
(Tough - that's all we had, if you want other cards supported get in
touch, and we'll see what we can do.)

Oh yeah, it needs a 386 too :-)

Command Line syntax:

CTHUGHA <-lmc> <-t #> <-r #>
	-l linein, -m micrphone, -c CD
	-t #  time for change in ticks (0-32000) (default 200)
	-r #  random ticks (0-32000) (default 750)
	      time delay formula : delay = t + rand()*r


Palette File Format :
The format is the same that FRACTINT uses.  If not all color indexes
are specified then they default to black.  The color values are
specified in RGB tupples (0-255), where 0 is black.  Easy !
The software scans the current directory for palette files (ext .MAP)
and uses up to the first 50 it finds.
Format -

255 255 255 comments index 0
