go further and he implemented the ability to customize player Avatars, first by patterning their clothing, and later allowing Avatars to change height, carry items, and ultimately to allow the players to select from over one hundred different heads for their characters, capabilities that are today taken for granted in other Avatar based systems. This feature became so popular that 'heads' were sold in in-game vending machines and were even used as rewards for players when they completed quests. With this outlook Morningstar and Farmer stated that a developer should consider providing a variety of possible experiences within the cyberspace, ranging from events with established rules and goals (i.e. hunts) to activities propelled by the user's own motivations (entrepreneur) to completely free-form, purely existential activities (socializing with other members). The best method to manage and maintain such an immense project, they have discovered, was to simply to let the people drive the direction of design and aid them in achieving their desires. In short the owners became the facilitators as much as designers and implementers. Regardless, the authors note the importance of separation between the access levels of the designer and the operator. They classify the two coexisting virtualities as the "infrastructure level" (implementation of the cyberspace, or the "reality" of the world), which the creators should only control, and the "experiential level" (visual and interactive feature for users), which the operators are free to explore. The user not need to be aware of how data are encoded in the application. This naturally follows from the good programming practice of encapsulation. Revival An effort is currently underway to relaunch Habitat using emulation of both the Commodore 64 and the original Q-Link system that Habitat ran on. The project is headed by Alex Handy, founder of The Museum of Art and Digital Entertainment (MADE), who received the game's source code from its original developers. In July 2016, the source code was uploaded by MADE to GitHub under MIT license for open review. In February 2017, an open-source project to revive Habitat led by Randy Farmer (one of Habitat's creators) named NeoHabitat was announced to the public. The project was requesting volunteer contributors to aid in developing code, region design, documentation and provide other assistance. Due to the volunteer contributors, original source files, maps created during development and database backups were unearthed. This enabled the original Populopolis world to be fully restored.
