Fellow Goglodytes,
I haven't done a treasure hunt in some time and I won't get around to one in a while. But I'd love for you to participate in a contest using a tool I recently finished.
The winner gets a copy of Cthulhu Saves Christmas
To play:
Download my MathArt game/tool: https://tallima.itch.io/mathart
Figure out how to use the program (try to start with numbers, then add functions to see their effect) and build a great Christmas-themed image.
The best image (my choice) delivered by December 1st wins the game so you can play a Christmas-themed game for a few hours in December!
Post your R=, G=, B= as well as your image and your setting. The winner becomes by desktop wallpaper for the next few winter months!
Some functions to try:
Green and red swirl (setting - Raw255):
R = 180+70*cos(6*a)*cos(r*12)
G = 120+100*sin(6*a+r*10)
B = 60+50*cos(r*5)
and
Winter blue swirls (setting - Raw255):
R = 50 + 40 * cos(6*a + r*8)
G = 120 + 80 * cos(6*a + r*8)
B = 200 + 55 * cos(6*a + r*8)
and
R = 255*max(0,(1.3*cos(6*a)-3*r)+(0.9*cos(6*(a+0.8*r))-2*r)+(0.6*cos(6*(a+1.6*r))-1.2*r))
G = 220*max(0,(1.1*cos(12*a)-2.6*r)+(0.85*cos(12*(a+0.8*r))-1.7*r)+(0.55*cos(12*(a+1.6*r))-1.0*r))
B = 255*max(0,(1.4*cos(6*a)*cos(12*a)-3.2*r)+(0.95*cos(6*(a+0.8*r))*cos(12*(a+0.8*r))-2*r)+(0.65*cos(6*(a+1.6*r))* cos(12*(a+1.6*r))-1.3*r))
I can't wait to see what the community comes up with!
I hope you a ton of fun nerding out with it!
P.S. I only have an .exe up right now. If Linux users can't get it working, please let me know and I'll get something rolled out.
