As my gift to all Anons, here's my 'hello world' in graphics programming.

#define N 10
int charge[N], xc[N], yc[N];

{
  for (int i = 0; i < N; i++)
    {
      charge[i] = -50 + random() % 100;
      xc[i] = random() % 320;
      yc[i] = random() % 240;
    }

  Address_set (0, 0, 239, 319);
  for (int x = 0; x < 320; x++)
    {
      for (int y = 0; y < 240; y++)
        {
          int ch = 1023;
          for (int i = 0; i < N; i++)
            {
              int dx = x - xc[i];
              int dy = y - yc[i];
              ch += charge[i] * sqrtf(dx*dx + dy*dy);
            }
          Lcd_Write_Data16 ((unsigned short)ch);
        }
    }

  delay (5000);
}
