There is also the possibility of an alien cog or gear.
On another note, my doctor gave me anitbiotics for my clinging bug, so hopefully I'll get better real soon now.
"Wabi-sabi (侘寂?) represents a comprehensive Japanese world view or aesthetic centered on the acceptance of transience. The phrase comes from the two words wabi and sabi. The aesthetic is sometimes described as one of beauty that is "imperfect, impermanent, and incomplete" (according to Leonard Koren in his book Wabi-Sabi: for Artists, Designers, Poets and Philosophers). It is a concept derived from the Buddhist assertion of the Three marks of existence (三法印, sanbōin?), specifically impermanence (無常, mujō?)"
"From an engineering or design point of view, wabi-sabi may be interpreted as the imperfect quality of any object, due to inevitable limitations in design and construction/manufacture especially with respect to unpredictable or changing usage conditions; then "sabi" could be interpreted as the aspect of imperfect reliability, or limited mortality of any object, hence the etymological connection with the Japanese word sabi, to rust."
