Process towards a world of entropy

Having the idea of a futuristic city/environment, the word entropy came to mind. So I went online to find more information about it, and I found one of the definitions very interesting to conceptualize. According to Wikipedia, entropy is the “measure of a system's tendency towards spontaneous change”. Out of that I kept speculating on “spontaneous change”, and the word liquid popped out. I became very interested in making the game’s environment in a constant physical and speed change, according to the player’s interaction with objects. In my mind it works perfectly fine, but I don’t how can I graphically do it or what technology to use. Any suggestions/commends/ideas/ will be gladly appreciated.

Here is some of Salvador Dali's painting that inspired me:
