Books and covers, my dear.
I would hardly call momentary novelties joy, especially not when "modern" society is thoroughly stuck in yesterday's advancements. Road and transportation infrastructure is in sore need of a redesign. Pulp nonsense like this is neither practical nor enriching beyond a momentary novelty. When your house is in order, you have time for these things. When your house is burning down, you shouldn't be jumping on trampolines.
