A few years ago I purchased a Christmas gift for a "young lady" I know.
(I am going to skip a bunch of stuff)
Well when it came time to set up Windows 10 on it I got her to enter her windows password and installed the Free Fireplace App. She heard it crackling and popping and finally looked and saw it... Her reaction was .. Well let's say it was well worth the cost and effort :).
Well the story does not end there.
She had to get up and do something elsewhere in the house. Left it running as a screen saver and when she got back her Cats were Cueled up in front of the "Fireplace"..
As I said. WELL Worth the effort
