forceimbalanceThe interesting about this place is that, even if on the other side of that excellently placed door he is distinctly lacking in corporeality, here Anakin gets to have his own body back again. Completely back, as he hadn't even since the start of the Clone Wars (let alone the darkest years of his life).
So there is a man who looks to be in his mid-thirties (he looks young for the age he died) with a few fairly nasty looking scars and a powerful presence in the Force sitting in a corner, tinkering away. In point of fact, he's working on a lightsaber design--Ezra Bridger's gun-saber specifically. An interesting idea, but clunky.
And so Anakin, perfectionist that he can be, is enjoying this chance to try to make it work.
