The /v/programming way:

#define BITS_IN_DATA 16
#define HEIGHT 42
extern uint16_t data[HEIGHT];
unsigned int x,y;
for(y=0; y<HEIGHT; y++)
for(x=0; x<BITS_IN_DATA; x++)
{
    if(data[y] & (((uint16_t)1) << (BITS_IN_DATA - x - 1))) // :D
        paint_black(x,y);
    else
        paint_white(x,y);
}

your welcome m8

Now with moar 1337 bro!

#define HEIGHT 42
typedef uint16_t data_type;
extern data_type data[HEIGHT];
signed int x, y=0;
data_type *ptr = data;
data_type bit;
while(ptr < data + HEIGHT)
for(x=sizeof(data_type)*8-1, bit = *(ptr++); x>=0; x--, bit = bit >> 1)
{
    bit & 1 ? paint_black(x,y) : paint_white(x,y);
    if(!x)y++;
}
