Thanks for reply! I am big fan of YC so this was really interesting question for me :) I believe workspace design is very important for great results and looking at YC backed-startups I was wondering which desk (and not only desk) are you using.

I'll definitely enter YC with some of my ideas at least ready as initial prototype (writing this using the moment). I hope I will like it so to make something similar in future to save this state of startup-spirit.
