# 2022 Update Notes **Additions for 2022 compared to the original 2015 version:** * Moved to github/gitbook * Re-organized content and added a new outline * Added new content and examples to almost every content page * Added separate sections for Legacy, Technique, and Experimental approaches * Added the following sections compared to the original, and dozens of new examples and videos. Most of the original categories also have many new subcategories within that weren't originally included. * Switchable Glass * Drone Displays * Many new Transparent displays and transparent OLED updates * Electrochromic Paint * Scanning Fiber Optics * Lasers and video projection * Laser Diodes * Many new Lightfield displays (Looking Glass, Solidlight, Fovi, Leia) * Architectural E-Ink * Ferrofluid * Acoustic Levitation * High Refresh Rate Displays * Cathode Ray Tube * Eggcrate and numerical displays * Pyrotechnics and other curiosities * Misleading terms * Touchscreen notes * XR and Virtual Production * ...and more? This is currently using Gitbook's free plan. If there is enough interest, I could set up a tipjar or something for this project and open it up as a paid project with multiple contributors and the ability to export the entire thing as a formatted PDF. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
