Subject: [alt-beam] chloroplast parts
I've been looking for a source for chloroplast parts, especially
34164-3s. I remember someone mentioned that they were available
from newark electronics (http://www.newark.com/),
and I'd like to
order from them cause they're near me, but they don't have 34164-
3s, a search just came up with a part called a MC34164D-005.
Anyone know if this is the right part?
main(){char x,y=-1,t,n,*c="-=+X# \baniel@crosswinds.net";while(++y<25)
{for(x=0;x<80;){float a,b,d,i=2.2/25*y-1.1,r=2.8/80*x++-2.1;t=b=d=0;do{
a=b*b-d*d+r;d=2*b*d+i;b=a;}while(++t<32&&b*b+d*d<4);for(n=0;t&~1;t/=2,
n++);putchar(c[x>79?6:y>23&&x<19?25-x:n]);}}}

Remember that light (measured in Lux) will drop about a factor of four,
for every foot(?? or metre....i cant quite remember) you move away from
the source. So whilst one photopopper might "think" it is in the
brightest light pool in a given area, there may be another light pool in
a near by area that is brighter at its source but just appears less
intense due to its distance from this bot.
