The BBC BASIC an 8-bit computer emulator.

BBC Micro bot runs your tweet on an 8-bit computer emulator.

The BBC BASIC - a language created by Sophie Wilson in 1981 for the BBC Micro.

You can share yor work like a tape or disk and test with a old computer.

This program will show a message and run commands on screen.

4 PRINT:PRINT " 64K RAM SYSTEM  38911 BASIC BYTES FREE"
5 PRINT:PRINT "READY."

Shadertoy: iChannel texture - 002.

In the last example I created a surface with a texture by channel inputs.

Now, I add a sphere distortion and sphere distortion with movement.

This is the source code I used:

#define PI 3.1415926

void mainImage( out vec4 fragColor, in vec2 fragCoord )
{
    vec2 uv = fragCoord.xy / iResolution.xy;
    // get poins 
    vec2 p = (2.0 * fragCoord - iResolution.xy) / iResolution.y;
    // set surface formula
    vec3 v = vec3(p.x, p.y, sqrt(1.0 - p.x * p.x - p.y * p.y));
    // create normals 
    vec3 n = normalize(v);
    
    // https://en.wikipedia.org/wiki/Distortion_(optics)
    vec2 sphere_distortion = vec2(atan(n.z, n.x) / PI,0.00000001 * p.y);

    vec4 color = vec4(0.0,0.0,0.0,0.0);
    
    if (uv.x > 0.0 && uv.x < 0.5)
    {
   		//color = texture(iChannel0, vec2(1.0 - (uv.x/0.5),uv.y/0.5)+ sphere_distortion);
        // with movement iTime
        color = texture(iChannel0, vec2(1.0 * iTime- (uv.x/0.5),uv.y/0.5)+ sphere_distortion);
    } 
    else if (uv.x > 0.5 && uv.x < 1.0) 
    { 
        //color = texture(iChannel1, vec2((uv.x/0.5),uv.y)+ sphere_distortion);
        // with movement iTime
        color = texture(iChannel0, vec2(iTime-(uv.x/0.5),uv.y)+ sphere_distortion);
        
    } 
	fragColor = color;
}

Stone Story RPG game.

An auto-RPG with strategic combat, deep crafting and programming elements, animated entirely in ASCII-art. In a realm of perpetual darkness, a single stone could change everything...see more on the Steam webpage.

You can see the graphic with ascii for this game on this youtube video:

Ubisoft and climate.

I don't know exactly how much they will solve in the future climate, but it is a nice gesture from the Ubisoft team to make people give up excessive energy consumption. Finally, a break and a reflection can be worth a lot in a few years ...

Take a break and you will be satisfied that you are not destroying your future with a disastrous climate.

Shadertoy: iChannel texture - 001.

In this example with shadertoy online tool I will show you how to map a texture from iChannel texture input and UV areas.

 void mainImage( out vec4 fragColor, in vec2 fragCoord )
{
vec2 uv = fragCoord.xy / iResolution.xy;
    
   vec4 color = vec4(0.0,0.0,0.0,0.0);
    
    if (uv.x > 0.0 && uv.x < 0.5)
    {
   		color = texture(iChannel0, vec2(1.0 - (uv.x/0.5), uv.y/0.5));
    } 
    else if (uv.x > 0.5 && uv.x < 1.0) 
    { 
        color = texture(iChannel1, vec2(1.0 - (uv.x/0.5), uv.y));
    } 
	fragColor = color;
}
