On one of the many HLN shows that are on in the evening and discussing the trial at great lengths, one guest (Marcia Clark, I think) last night discussed that several of the jurors were slumping over their knees to stretch during the many sidebars yesterday and she said that this was because yesterday's testimony was lackluster and there were too many sidebars. But other than that she believes the jury is doing a great job at paying attention to the details and absorbing it all.
