My implementation of Pic in Go. Part of the Go tour: http://tour.golang.org/#35

Pic.go

package main

import "code.google.com/p/go-tour/pic"

func Pic(dx, dy int) [][]uint8 {
    
    picData := make([][]uint8, dy)	
	
    for y := range picData {
        picData[y] = make([]uint8, dx)
        for x := range picData[y] {
            picData[y][x] = uint8(y+x/(x+1)) // this function draws a relaxing gradient
	}
    }
	
    return picData
}

func main() {
    pic.Show(Pic)
}
