I found some amazing carpet floor tiles at flor.com. I was never a big fan when they first came out, they reminded me something you would see in a doctors office. The new designs are really winning me over. I'd like to update the the carpet in the Foyer and under the dinning room table, two areas that get quite dirty. I'm really liking the black and white stripes (featured in the first picture). Also the website allows you to buy samples, 3 for $5.
