for i = 1 to 100 loop
    // Pick random colour
    col = { random( 101 ) / 100, random( 101 ) / 100, random( 101 ) / 100, random( 101 ) / 100 }
    x = random( gWidth() )
    y = random( gHeight() )
    width = random( gWidth() / 4 )
    height = random( gHeight() / 4 )
    outline = random( 2 )
    box( x, y, width, height, col, outline )
    update()
repeat
// Wait 3 seconds
sleep( 3 )
