1) Go to page http://tour.golang.org/#35
2) Clear the existing code in the window
3) Copy and paste the following code (between ‘Begin’ and ‘End’ lines):

```// === BEGIN ===
package main

import (
//"fmt"
"math"

try_slice := make([][]uint8, dy)
for i:=0; i<dy; i++{

for j:=0; j<dx; j++ {

// initialization to light color
// Note: 255 is light and 0 is the darkest
try_slice[i][j] = 230

// Printing of 'I'
if i > (dy/2-40) && i < (dy/2 - 10) && j>=20 && j<23{
try_slice[i][j] = 0
}

// Printing of 'heart'
// Thanks to http://www.intmath.com/blog/i-heart-math/5179

x:= float64(j - dx/2)/float64(dx/4)
y:= float64(dy - i - dy/2)/float64(dy/4)

if math.Pow(float64(x*x + y*y - 1 ), float64(3)) <= x*x*y*y*y {

}

// Printing of G'
if  i > (dy/2-40) && i < (dy/2 - 36)  && j>= dx-40 && j<dx-27{

}

}
}

//fmt.Printf("%v\n", try_slice)

return try_slice
}

func main() {
