What if, you could capture a special moment or wanted to rescue something precious to you if it was impossible to do it Physically? Allow me to introduce the Stasis Cubes! With this, you can capture a moment in time and space, and it will become a 3D Oil Painting when you use it. It can work on Mobs, Objects, Players, etc. It won't freeze the player, it will just capture that moment in a 3D Image you can place on your wall. It would also give the Holograms more use, if you don't want to become part of the actual painting. 

Also, for a more exciting effect, Mobs such as Cybermen, Daleks, Gallifreyans, etc, can eventually break out if they become self-aware of where they are.

the Stasis Cube will have a limit of uses depending on what it is used on, if it is used on capturing selfies or such, very little power. capturing planets or cities will give the cube a limit of 3 uses.

I am sorry but I really don't know what else to write, so I'll put any other info below.

Picture: 

IF you want to save your structures from being griefed, save it via Stasis Cube.

As for the Time Lock future, this will Freeze an Entity for as long as the Lock is active. if broken, everything is released from inside the Time Lock. if you yourself, however, are in the Time Lock, you'll be inside a Black Darker Version of the place you were in when it became active. in order to escape, you need the help of someone else to break the Time Lock. however, they can't enter the barrier of the Time Lock, so you'll need to use your Sonic to get them out.

I didn't explain this much, but I am really tired. I'll have another suggestion done when im more awake.

I like this idea, but some of it seems a little much for MC to handle, idk.

 I'm sure they can find a way. not everything is impossible...however...now that I think of it...freezing entities will make MC hardly playable because they could freeze anything...

great idea,  but going along with duckduckgo  it would be alittle hard for minecraft to handle,   also difficult for the 1WTC    and the rest of the developers to code.

also,   if you want other people to see it,  you'd constantly have to be updating the dalek mod for each scene you capture,    otherwise the  other players wouldn't be able to see it  ( unless you were intending for the scenes to only be view-able by the person who saved them )

 Not impossible, just very very hard, and it might not be worth 1WTC'S time. He's the only one who is coding the mod after 2 members left the team. So why code this extremely hard function while they can just add a few more other features?

1 great feature > a few "meh" features.

I like this. I really, do.

Points for creativity and originality on this one.

Also for just being a pretty cool idea

What Arc said, I think this is the first time someone suggested this xD

I've definitely never seen this before, I love this idea. It's got my support. If you think about it, it's sort of like a time locking Pokéball. xD
