Wonderful colors - and I'm pretty sure it is a Coleus plant: Coleus - Wikipedia, the free encyclopedia You can find images that look to be the same type as yours by searching Coleus. I don't normally know too many plants but some Coleus plants are grown indoors... I have memories of being in college apartments filled with them.
As soon as I saw this photograph, the thought "It's alive!" came to mind. To be fair, that's a quote from "Frankenstein" when Dr. Frankenstein realizes the monster is truly alive! And even though we know that all plants are truly alive, there is something a bit unnerving to me when I look at this vine climbing up the wall... It's as though it's trying to break in through the duct work. Great color, Christian! I like this photo but it does give me a sort of eerie feeling.
