Last weekend, I went up to Berkeley to measure my new tiny apartment room to decide what furniture my roommate and I would be able to fit in it.
Trying to work out the measurements on paper, I was inspired to build an application to do it for me (because why do something in 10 minutes when you can build something in 15 hours to do it for you?).
I quickly pulled this application together in a day or so, using JQuery UI's draggable and droppable handlers. Currently, the application supports: editing the room size, creating flat lines for doors/closets and rectangles for beds/desks, dragging objects around with snap-to-objects and snap-to-grid, and rotating and deleting objects.
Please check it out and tell me what you think!
