Not really something looking like a game but a topic about that kind of program should be done. I toyed with TCOD and simplex noise. I did a simple perlin-like noise to 8 gray scale + position dithering. Here is the coordonate dithering method. You can change the 4 into any power of 2.

Code: (c) [Select]
int u = x&-(4-(x&1));
int v = y&-(4-(y&1));

EDIT : here is the actual code. you'll need TCOD, which seems to be a pretty nice roguelike-based terminal emulator+utilities library
Spoiler For Spoiler:
Code: [Select]
#include <math.h>
#include <iostream>
#include <libtcod/libtcod.hpp>
#include "OpenSimplexNoise.hpp"

float step(float value, int steps) {
if(steps > 1) --steps;
return (int)(value * steps)/(float)steps;
}

float clamp(float value) {
float result = value < 0 ? 0 : value;
return result > 1 ? 1 : result;
}

int main(int argc, char const *argv[])
{
OpenSimplexNoise noise(0);

TCODConsole::initRoot(80,50,"Open Simplex Noisem",false);

bool done = false;
int t = 0;
float scale = 1./50.;
float timescale = 1./600.;
while(!done) {
TCODConsole::root->clear();

for (int x = 0; x < 80; ++x)
{
for (int y = 0; y < 50; ++y)
{
int u = x&-(4-(y&1));
int v = y&-(4-(x&1));
float value = 0;
value += noise.value(u * scale, v * scale, t*timescale );
// value -= noise.value((j&1) * scale, (i&1) * scale, t/100.)/3;
value = ((value + 1)/2.);
value = clamp(value);
value = step(value, 8);
int pixel = value * 255;
TCODConsole::root->setCharBackground(x, y, TCODColor(pixel, pixel, pixel));
}
}
TCODConsole::flush();
t++;


TCOD_key_t key;
TCODSystem::checkForEvent(TCOD_EVENT_KEY_PRESS,&key,NULL);
switch(key.vk) {
case TCODK_ESCAPE:
done = true;
break;

default:
break;
}
}

return 0;
}

I won't spare you from that one. Not seriously, read that. I totally got off guard.

I'm getting more and more used to my new computer. Here's the current desktop look. I have two 1280*1024 screens and the split between them is right at the right place. I wanted a wallpaper that would be splitted in two and yet I found something that went beyon my expectations : let's get retro with Spy vs Spy! :p

Code: (c) [Select]
depression_points = {LIFE, SHYNESS, LIFE_CHOICES, LAZINESS, etc...}; // too many to list them.
while(has_projects_to()) {
    if(has_homework_to_do()) {
        if(has_important_project_to_do())
            program_on_small_project(rand()%num_small_projects());
    }
    else
        depressing_about_(depression_points, rand()%num_depression_points());
}
EDIT  :oh wait that isn't humourous nor a joke... WAit...

Code: (c) [Select]
while(it_wont_work()) {
    if(rand()&1)
        depress_about_it();
    else
        try_to_desesperatly_fix_it();
}

... Damn!

Nah, it won't be. Pokémon sprites 3th gen up to 5th are quite detailled and have up to 16 colors.
