I defy anyone who does not like Pixar and all that it entails: the films, the concept, the imagination and of course the Easter Eggs. Easter Eggs you say? Yes, Easter Eggs!
In this context Easter Eggs are those things which appear in each and every (nearly) Pixar movie. For example the Pizza Planet Truck which we know from Toy Story, but can be found in all other films apart from The Incredibles. This video, along with 2 others, goes through and identifies all the hidden Easter Eggs. You’ll constantly be looking out for them now!
This is something which Disney also does, definitely worth a Google.
If you have a certain message or logo, maybe this is something you could apply to your business?
