Roblox Hack Week/2011

Roblox Hack Week 2011 took place in late December of 2011. It was the first Hack Week in Roblox history, and featured four different tech demos that would later all be fully implemented into Roblox.

Game Universes
This demo, presented by, features the ability to link multiple places under a singular "universe". In addition, progress in one place in a universe would effect NPC or world interactivity in other places within the same universe. All data persists across places in the same universe. The tech shown in this demo was later implemented in full on January 31, 2014 as game universes (now known as experiences).

Water, Buoyancy, and Ropes
This demo, presented by Dan Ignatoff, Erik Cassel, and Tim Loduha, features buoyancy for objects in terrain water depending on their mass properties and material. The demo also included ropes, which could loosely keep objects connected. The tech shown in this demo was later implemented in full after the addition of s on April 27, 2016.

Shaders and Dynamic Lighting
This demo, presented by Simon Kozlov, features more realistic shading and dynamic lighting. It also included the ability to export Roblox Studio models to 3D model formats and vice versa, but this was not the main focus of the demonstration. The tech shown in this demo was later implemented in full.

Video thumbnails
This demo, presented by Tim Brown, features the ability to add and view YouTube videos on a place's page alongside other image thumbnails. The tech shown in this demo would later be implemented in full.
