I was at Nesscliffe through most of the day too - there was some very impressive climbing going on! It's well written up elsewhere.
Marcus's photos are great and in reply to the last comment, the routes are as follows:
Photos 1 and 2: James Pearson on Gathering Sun, E7 6c.
Photo 3: James on My Piano, E8 6c (on sight).
Photos 4, 5 and 6: Looks like Hazel Findlay on Yuckan II, E7 6b.
