Another possible idea, is a
"picking mushrooms" mini game with grigori perelman, where rather than pick the mushrooms, you fend off the relentless assaults of the fields' medal prize comittee attempting to disturb perelman in his quest to pick them.
Unfortunately, perelman is very much still alive, so that might be too risky of a minigame to add without a disclaimer.
(Perelman received some "clearly unwanted" attention a few years ago for completely stomping one of the hardest, and at the time, still unproven mathemtical conjectures in the entire field of mathematics, known as
the poincare' conjecture. Essentially, the conjecture was that one kind of manifold (3d topology) can be used to describe a different manifold, as long as certain criteria are met. (Eg, you can describe a cube as if it were a distorted sphere.) *this proof of the conjecture directly impacts my vocation, as I do 3d CAD/CAM work, and this proof can help improve the software we use, amongst many other things.* Perelman staunchly refused all interviews, refused the prize money, and refused to give any speeches regarding the proof, citing that the math itself was the prize, and everything else was worthless vanity and posturing with no value. (He appears to find the pursuit of prestige to be unimaginably vulgar, to the point that he sees mathematicians attempting to tackle hard problems, soley as a vehicle for attaining the prestige, as a cardinal sin. He seems to view the mathematics itself as the purity to be sought, for its own sake.) Despite this however, the fields medal prize comittee relentlessly attempted to contact him to award the prize and prestige he had repeatedly told them he didn't want, even going so far as to interrupt a mushroom hunting excursion he and his sister had undertaken by blowing up his cellphone.)
