额 = 客 + 页 : Albert Einstein (Ø) and his guest (客) are playing a game of 20 questions just inside the elevator's kitchen (e2). They both have sheets of paper (页) fixed to their foreheads (额) with a name on each to guess.

尔 = ⺈ + 小 : Mnemonic symbol derived from the components: a peace dove. Albert Einstein (Ø) wants to send a message of peace to earth from the space station's living room (Ø3). He wanted to give a dove (尔) a daisy (小) so that it can bring it to earth, but the dove is late! Albert has no choice but to give it to a passing crane (⺈) instead. Thus, the crane flies to earth with the daisy in his beak, just like a peace dove.

古 = 十 + 口 : Mnemonic symbol: at least on German maps, this character actually resembles a cloister.

Oh no! Gitta Giraffe (gu) found that the golden cross (十) broke off of the cloister (古) in the space station's living room (Ø3)! She skewers a mandarin (口) on top of the cloister so that she can skewer the broken off cross back on to fix it.

纳 = 内 + 纟 : Napoleon (n) took a tiny CT scan (内) of the silk worm (纟) in the ashram's bathroom (a4). The silkworm is relieved when it receives (纳) the scan and realizes that everything is ok.
