I had an idea while looking at my iguana today. Although the iguana can walk around, climb, even stand on two legs and beg for things, its natural state is to lay out flat and bask for 90% of their day. People prefer to sit in chairs or lay in beds when they are not doing physical activities. Is their any way this could be reflected in the diplomacy screens for the alien ambassadors? Humans sit in a chair, water-creatures would appear in water (or a "fishtank room", etc), some creatures might like to lay on pillows, or suspend from a hanging chair/bed, or maybe sit on a pile of shiny stones, who knows?
I thought this might add something to the races, if all the diplomacy media hasn't been done already.
