Lots of family time over the holidays and not much time off work, but I managed to get a few things accomplished in the HT.
First, the gift from the Mrs. 4oz tabletop popcorn machine. Works great and the Great Northern Popcorn premeasured packs taste just like movie theater corn IMO.

Now on to the theater updates. Cut the vent holes for the riser, and wired up the step lights.

Installed the brackets for the surround speakers.

Installed 2 layers of Linacoustic RC behind the screen wall.

Columns are next. Should be able to get to those this weekend.
