Deb suggested doing something more between rounds.

Apart from showing a timer counting down to the start of the next round, we can show the puzzles of the round that just ended highlighting the theme of the puzzles (along with author's name). Players usually miss the themes until they revisit the booklet. They also need to wait for the booklet (and its solution) to see the theme and author.

This is very good idea. Also in the dinning area or in any other area if we have projector there we can keep showing photographs taken during current WSC/WPC or may be taken during previous WSC/WPCs.
