Here is a poster I made which shows 1 million dots on a single page. One of the dots however is red; can you spot it?
To view the poster in Microsoft PowerPoint: right-click on the link below, select ‘Save Target As…’ and save the file to your computer. You should then be able to open and view the poster as you would a regular PowerPoint presentation.
Thanks to this website for providing the 10,000 dots template which I used for this poster.
