[kwlug-disc] Pictures -> room dimensions, decorating, room planning?

[unsolicited]

I haven't found it, but seems to me Richard mentioned something some 
time ago about taking a picture of a room and software magically making 
a 3D model out of it? Or something? Richard?

In any case ... am I dreaming or have I heard about some software to 
which you can feed pictures, then it lets you move furniture all about 
within the room, try different wall colours, and so on?

Anyone know / used / ???
