I've been trying to figure out how to decorate and arrange the furniture at the new apartment. I got tired of trial and error on paper, so I got out the Sims and tried that.
It isn't exact, but it is faster to just point and click than it is to erase and redraw. It isn't 3D Home Architect, but it is a whole lot cheaper. And you can play with the people after you're done arranging too.
The thing by the white couch is a computer armoire. I haven't found it yet, but I'm going to get one anyway. I have found a round glass-top table for the dining room. I'm not going for the blue formica, despite how good it looks in the Sim version.
