Has anyone seen the magnetic stones that Michael Redmond used on the demonstration board for the Deepmind match for sale somewhere?

They are double sided black/white, similar to othello stones. Seem superior to the normal demo stones.

This what you're after? Have used pentangle for books and their service was good.

The set in that link has two separate sets of stones. It is also not clear as to how big it is. I have a demo board which is about 3 foot square and has two sets of stones, one black and one white. I think that is probably what Redmond was using in the commentary.

Still officially AGA 5d but I play so irregularly these days that I am probably only 3d or 4d over the board (but hopefully still 5d in terms of knowledge, theory and the ability to contribute).

It was quite clear from the stream, that Mr Redmond's "stones" were white on one side and black on the other.

Good point! I noticed that stones too, that‘s a great idea: it solves the everytime problem of having the wrong colour stone in your hand when re-creating a position.

I tried some research in the net looking for the following words:
Othello/Reversi + demostration + magnetic board
with little/no success.

Seems that it is not so standard to have Othello classes like we are used to have for Go
So I was resolving to create a self made set (i.e. asking someone with the right ability to do it ).

Those aren't two sided stones (except by the definition of not having exposed magnets)

The stones Michael Redmond have been using has white on one side and black on the other side of the same stone. Very cool!

Ah, these are. Can you find the larger ones too?

Thanks everyone, particularly Jujube, Kirby & xed_over.

I think you are correct that these are the ones by the looks of things.
