Help me identify an optical illusion where abstract blotches of color on a page turn into words/an image when viewed from the side/edge of the page.

I remember seeing this visual effect somewhere when I was younger - when your point of view is perpendicular to the page, all you see is abstract art, but as your viewpoint comes down parallel to the page, letters and words appear out of nowhere.
The effect is similar to this image
, but I remember (and am looking for) something that I could duplicate by hand - I thought this would be a neat technique to use on a costume sword, so words appear when you're looking down the point.
Other avenues of research have lead me to things like forced perspective techniques and Anamorphosis
Identification of the kind of effect this is would be swell - most of my searching has come up with illusions dealing with relative size of perceived angles. References would be useful, especially if they provide details of 'how it's made' for me to reference.
