The Daily Politics is testing the mood of the delegates at the Liberal Democrat, Labour and Conservative parties.
For the third year, a few coloured balls and plastic bins - we call them a mood box - are being used in a series of unscientific polls to see what party members think about key issues.
The delegates are asked a question of the day - by Adam Fleming or Giles Dilnot - and then vote by using their ball and we have a look at the end of the vote to judge the mood of the conference.
All of the videos will appear on this page and also are being used on the Daily Politics website.
