There's the Entropic Fields piece that fits in the 1x1 field. Play a few times and you should see it come up. It's a pretty useful but chaotic combination with Agoraphobia.
Ah, I see! Just got the combo and it's pretty fun.
Though - Entropic Fields seems to always pick a piece to click deterministically (ie always picks the same piece for any given layout, I think the top left one?), I wish it chose at random among all clickable pieces
