I used SweetHome3D + Gimp to recreate my whole home!

Lots of measuring and downloading textures and models, but I finally have a digital 'clone' of my home!

The lights all react to changes in color and brightness, and are clickable. I made the buttons transparent so it looks cleaner.

Thermostat is in the center, if clicked it opens the thermostat options. The background glow of the temperature turns blue when cooling and red when heating (black when idle)

My 3D Printer can be turned on by clicking on it too, plus it shows the current progress if it is running.

I'd love to see other people's floorplans for ideas, comment with a pic if you have one set up!

Wtf, does it do some primitive form of ray tracing to figure out how the lights bounce around the floor plan? That’s sick!

Here I am using Apple home like a loser

SweetHome3D does that part.
You export an image for every light, where its the only light on. Everything is black except where the light shines. Make those black parts transparent in Gimp or PS.

now when you layer them you have each light's beams all intersecting and mixing.
There is a background image where all lights are off that they all stack on top of

Its far simpler than you might imagine.
