Torque 3D 'toys' or demos

I've been wanting to do this for a while, and the idea has been brought up again, and people liked it, so let's have a discussion here. T3D should have some really basic levels that demo different engine features in a clear, concise, and easy to understand fashion. Whether it's setup of art objects, ideas for script functionality, or just examples of engine features, each level should have a very tight focus and be well-documented.

I'd like to propose a couple of things.

• This demo application should replace the current script templates in the repository. The script templates should be split into separate projects.
• The demo application should be based on t3d-bones, or something like it.
• There should be full editor support. Somehow.

So what demos should we make? What should the UI look like? Are there good examples out there from other engines?

EDIT: My favourite ideas so far:

• Physics shapes
• Lightmapped object
• RTS selection/movement
• Breakable objects
• Basic AI: follow, attack, pathfinding, dunno what else
• Vehicles
• Player (i.e. how to set up all the animations)
• Melee attacks (first-person and third-person)
• Ribbons
• Custom materials/shaders
• Custom postFX
• Triggers (teleport?)
• Animated door with collision (triggered, direct interaction, indirect interaction)
• GUI quest counter (i.e. logo collection)
• NPC dialoge box GUI
• Different ActionMaps
• Tweening using Twillex?
• How to make prefabs
• Simple inventory?
• Particle emitters
• Internationalisation
• Precipitation
• Terrain and GroundCover
• Twillex
• Water
