I guarantee you will be as hooked on this as I am. Floorplanner takes those mediocre house-plan / design packages out there (including the really crummy online, browser-specific, super-crashy versions like Home Despot's) and puts them all to shame. First of all: it works. All the time. In every browser I've tried it in. It's fast, colorful, has an enormous number of colors and patterns available, lots of furniture, easy wall / door / window / angle drawing tools, and it's just so much darn fun! Plus they are constantly adding new tools and objects. Play with it and email me your best Craftsman creations - I'll put them up on Flickr!
