There's actually a fourth camera - viewing from an avatar's eyes - but it's no longer open to Watchers. There were too many fights over avatars looking the wrong way than a Watcher wanted to look.
I'll be taking down the wallpaper offer this weekend, so if you wanted it, now would be your last chance. I'll be putting up a new one, though! It'll show up come next update.
As for incentive, I'm going to post it up on October 1st. The voting resets every month and your votes would be more helpful on the first than on the last day of the month. Hope you all don't mind! Of course, if you want to vote today, please feel free to do so!
I'll edit this post when the incentive is up
EDIT: Incentive is up!
Thanks to all who vote! And thanks for reading my webcomic!!
