MicPaint v1.0

MicPaint is a program that runs on PCs with VGA graphics and a sound
card with a microphone input port. It produces interesting graphic
"artwork" from samples entering the analog to digital converter of the
sound card. The program works best on fast machines, since the graphics
routines implemented here are not very fast.
As some may recall, a few years back, I remember hearing of a TV show
where a monkey was allowed to produce modern art. This monkey had a
paint brush tied to its tail (or something like that) so that when held
against a canvas, the monkey's movements produced various swipes of
color on the canvas. A hidden camera recorded the excitement of art
critics who viewed the "works" after the monkey had been let out of the
room and the canvases were properly framed. Of course those strokes,
the brash and unpretensious use of the brush, signified genius. Today,
the Monkey's portfollio is being auctioned at various places, including
Sotheby's in Los Angeles.
MicPaint was designed to emulate this great Monkey genius. Yet, it is
quite different. It picks up sounds (or whatever other signal impinges on
the ADC port) and displays the samples in various ways on the graphic
"palette" of the VGA screen. Of course, this is an update to Radio
Shack's famous "disco lights," although I prefer to think that MicPaint
is a bit more in tune to Hip Hop and Rap (note the "grafitti mode") input
than the aforementioned.
USE: You will need a computer with a VGA graphics adaptor and a
sound card with an addressable ADC port. I wrote this program on a 486
computer with a Covox SoundMaster II. The SMII has an ADC port on my
machine at 22f (hex), so the default port for the system is defined for
this. However, you can override this by using the -p flag at the
command line. The program will then display its artwork in 256 color
VGA graphics. So, turn on the local pop radio station and crank it up!
Then, invite friends over, turn off all the lights and turn on MicPaint.
And please, don't feed the monkey!
P.S. This program is freeware. Pass it on and have fun!
