極大值

极 = 及 + 木 : As Joan of Arc (ji) and Yuwen Huaji (及) pass over the north pole (及) at Christmas just inside the space station's entrance (Ø2) they decide to celebrate this moment by having a little contest. Between them there is a rather large Christmas tree (木) and they decide that whoever climbs to its top (极) first is the winner.

大 = 一 + 人 : The big (大), huge (大) robot (mnemonic symbol for 大) is working out in the ashram's bathroom (a4). He's lifting a flute (一) to which Don Quixote (d) and Neanderthal man (人) are clinging.

值 = 亻 + 直 : James II of England (zh) joined the straight edge (直) scene, and he decided that everyone else should too. Just inside the space station's entrance (Ø2) he tells any visitor that it's not just worth a try (值), but that anyone who isn't straight edge is not worth (值) entering. Even Rosa Luxemburg (亻) has to get two crosses tattooed on her hands before James II of England thinks she's worth (值) to enter.
