My sim is a mad scientist now ( level 10 Science career ) and now he can experiment on some objects. Sometimes make a couch look better, it gets a glowing circle around it or it catches fire when the experiment fails. Other objects start to make music or a annoying sound. But it can also improve an object, like a fridge can hold more items, and a shower cleans the sim faster.

If they visit the theater you get the option "woohoo backstage" it's the only one I found so far though, maybe there are more places but i'm not sure.
I want more different plants for in the house, 2 and 3 story columns , one tile spiral staircase, and a lot of the other buildmode stuff created by CC makers.[/list]
