工 = 二 + 丨 : Mnemonic symbol: a steel beam, since 工 looks like the cross section of a steel beam. In front of the engine ((e)ng1), Gitta Giraffe (gu) is doing some hard work: She's stacking a capacitor (二) on a dinosaur bone (丨) on a capacitor (二). She's not very successful, but then she gets the idea to use steel beams (工) as support.

智 = 日 + 知 : In the space station's bathroom (Ø4), the sun (日), Francis Bacon (知) and James II of England (zh) are competing for who's the most knowledgeable of them.

慧 = 彗 + 心 : Someone broke Helga Horse's (hu) heart (心) and shattered it all over the Eiffel Tower's floor (ei4). Helga Horse is very wise (慧) and knows not to fall into despair over it. She sweeps her heart together with a broom (彗), puts it together and prepares for a new start.
