I'm creating a Patreon article on the most innovative virtual worlds in VRChat, but this new one deserves its own post right now:
NeoWorlds, created by "Widget365", is a virtual world created within the virtual world of VRChat -- which looks and plays like a low-res 2.5D virtual world of the early 2000s era. (Think Habbo Hotel, Club Penguin, and so on.)
There's even an old school web-based log-in page for NeoWorlds (cosmetic only), and a log-in experience which starts you in front of an old school, desktop PC and cabled mouse of the era (see video above).
All of which is so on-point visually, it induces nostalgia. Where it really gets mind-boggling is when you "log in" to NeoWorlds, and realize your VRChat avatar has been faithfully converted into a low pixel, 2.5D version of it -- which you still control.
I just tried it myself, and my current VRChat avatar, a tribute to Domo-kun (long story), was suddenly waddling around before me in pixelated form. (See right.)
How did Widget create this? Read on:
