This would most likely be 2.0 only, but with tags 1.0 objects might work too
Basically What if you where able to recoler shapes with circuits with a tag or the definition board the choose what material and coler you would change it to and then press a button and the color of the object or even the button changes material.
Examples of 2.0 ver.
Examples of 1.0 ver.
This would be helpful for a variety of things like skins for weapons without needing to make a new object for it or to make a verity of other things!
Edit.
This is an updated version i just made because of the reddit post i made about this here

Basically i re-did the circuit to make it look better and remove unnecessary stuff
i also was told that the materials input doesn’t exist and is actually an int input and i did know this but i honestly dont like it so its not in my new example
And you can use the rec room get object with first tag but i added the tag in the new example anyway! I also forgot to take it out 
New example:
