-- Break the sentence into a table of words
local wordTable = {}

--set the scale so we can print one word on each line.
for scale = 5,0.5,-0.5 do
    attachedMonitor.setTextScale(scale)
    width,height = attachedMonitor.getSize()
    if height >= #wordTable then
        print("Scale ="..tostring(scale))
        break
    end
end

-- scale is set, and we know width and height.

-- set a random background color

attachedMonitor.setBackgroundColor(backgroundColorTable[math.random(#backgroundColorTable)])
attachedMonitor.clear() -- will repaint monitor background

-- For each word, print it on a line in a random background and random text color
for line = 1,#wordTable do
    local word = wordTable[line]
    -- set a random background color
    attachedMonitor.setBackgroundColor(backgroundColorTable[math.random(#backgroundColorTable)])
    -- set a random text color
    attachedMonitor.setTextColor(textColorTable[math.random(#textColorTable)])
    --set a random column for our line position
    attachedMonitor.setCursorPos(math.random(width-#word),line)
    attachedMonitor.write(word)
        sleep(1)
end

-- reset monitor colors
attachedMonitor.setBackgroundColor(colors.black)
attachedMonitor.setTextColor(colors.white)
