We recently built a home theatre in our upstairs bonus room. I took timelapse videos of each day's work, finishing with exactly 100 videos roughly 30 seconds each, taken over a 3 month period. Videos were merged together and sped up by 50% to create a 30-minute video showing approximately 100 hours of work.

Full build details and photos are here:

This build is nearly an exact replica of the theatre I built in our previous home 2 years prior: https://www.flickr.com/gp/akahige1/07...
