Narbacular Drop. Same concept as Portal's portals.

引用自 Wikipedia
Valve Corporation, developers of the Half-Life series, discovered Narbacular Drop after its release and hired the entire development team to work for them. The team developed Portal, that shares some things with Narbacular Drop's concept.

Tag: The Power of Paint. Same concept as Portal 2's gels.

引用自 Wikipedia
These gels were created by the team from the Independent Games Festival-winning DigiPen student project Tag: The Power of Paint.

And both of them are free.
I see that Conversion is on this list. If i remember correctly, Conversion is free on steam, but you need to buy Portal 2 to use it.

Still works on the list though.

I just remember about Whitewash. It isn't on Steam yet, but it's already greenlighted.

And Twin Sector

Check out Q.U.B.E. on Steam. The link is broken so just search for it.

They don't sell the original version anymore, but the director's cut edition works.
