Saw these cool looking new heating pipes in basement

I have a basement with relatively low ceilings and it is not helped by hot water heating pipes that hang about 5 feet off the floor. SOme day I want to finish this basement.

The other day I was at my neighbors (same basic house) and a few years ago they had all of their hanging metal pipes replaced with this really cool looking seemingly flexible tubing (enough to route it up in between the joists). It is sort of a clear bluish color tubing, maybe 1.5 to 2" thick and connects to the old steel pipes via this neat looking copper sort of transitional fitting. Anybody know what this stuff is, where I can learn more about it and if it is something one could purchase and work with (DIY)?

What you saw was most likely PEX (crosslinked polyethylene).
If you use it for a heating system, make sure it has an oxygen barrier. BTW, blue is usually designated for cold water.
