Art
With the wide array of colors available for Post-it Notes, it's not surprising that someone figured out how to use them as an art palette like paint. The detail in some of these works of art denotes a great level of talent and patience.
From something as simple as an 8-bit version of Super Mario to an Andy Warhol-inspired Elvis Presley rendering to an exquisite and intricate depiction of the Mona Lisa made of 12,000 sticky notes, this cool use of Post-it Notes is only limited by the artist's imagination.
Pranks
Some of the pranks pulled with the use of Post-it Notes are funny yet time-consuming to the prankster. Most of these pranks involve covering something with an inordinate number of Post-it Notes.
One popular viral prank from 2008 involved a faction of 12 people who spent two hours covering a coworker's Jaguar with 14,000 Post-it Notes of varying colors. This prank caught the attention of 3M, which copied the idea in an advertising campaign.
Waterfall
Creating a waterfall is very simple with the invention of zig-zag sticky notes, which alternate position of the adhesive from top to bottom. Zig-zag notes are developed specifically for pop-up sticky note dispensers. When these notes are pushed over the side, they create a waterfall effect with Slinky-like characteristics.
The guys from eepybird.com created a three-minute video involving numerous Post-it waterfalls made of over 280,000 notes. This video won them a YouTube Webby Award in 2009.
Stop Motion Movies
Many of today's movies use CGI and 3D technology to make effects look more realistic. Yet, simpler animation techniques, such as stop-motion, survive because there is still a place for them.
Post-it Notes have been used to make short stop-motion movies that can be both thoughtful and silly.
One popular example is a short called "Deadline" about a man trying to work on some unnamed project on his laptop while a Post-it wall in front of him recreates his mental state during the course of the video.
