I have been experimenting with augmented reality illustrations recently, incorporating floating layers and animated sections.
Using Procreate to create the original artwork, and After Effects to animate some of the layers I constructed the final AR part using the Artivive App. Pointing the Artivive App at the basic trigger illustration will allow you to see floating semi-transparent ghosts, the candles light up and the sea becomes animated.
Both the basic trigger illustration and composite version can be found on my website. A video of what it all looks like is also on my Vimeo.
