Think "Flag not Banner"... :-) Then you can get somebody to march around with the flag raised high when you're collecting people and then, when enough are present to be a "group", you stick it in the ground and fly it proudly above the assembled masses.
Seems to work well enough in Rock Festivals amongst 150,000 people so I'm sure it'd work fine too in a relatively sparsely populated Hyde Park :-) Sean -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
