Special effects stickers

There were all kinds of special visual effects that stickers offered in the 1980s. They quickly evolved from two-dimensional decorative seals to collectors' items with a range of sensory bells and whistles: puffy, fuzzy, scratch and sniff, shiny, sparkly...

And the eighties were a time of special visual effects. You could get sneakers with "oily" rainbows on the side, wear fluorescent clothing, and affix glow-in-the-dark stars to your ceiling. The time was ripe, I think, for stickers that could be marketed as "opalescent":

So pinky and pastelly, too. And let us not forget holograms!

A scientific brainchild of the 1980s [note: actually 1968], holograms combined rainbow and 3-D effects in one. So cool. We've got balloons, unicorns, bears, James Dean, and Marilyn Monroe...

The greatest special effects stickers were probably liquid crystal (or "oily"). Some of my oilies have aged; you have to periodically massage them to keep them fresh.

Finally, check out the awesome heart--I am not sure what you'd call it, if it's not holographic. Here is the view at an angle:

The three-dimensional pattern appears to extend into infinity; the image actually changes with the viewpoint of the observer. Such a space-agey, computer-graphics inspired take on your classic heart sticker. Like Tron meets Hallmark or something.
