I with a bunch of friend were talking about an adventure game. there will be too many possibilities in the game and the player can pick from wide varity of choices at each stage to do somthing. there will be consequences for each decision and they may or may not end the story. the result would be somthing like (picture from flashforward series S01E17)or if any of you watched hereos season 1 there is also similar time lines represented as strings in isaac mandez workshop. sorry for bad quality examples but right now I can't think of any better one.

do you know any website or application which we can use to create the timeline? these features the least required ones:

• the ability to represent events as boxes.
• the ability to connect distant events to each other.
• the ability to move events on a scene freely
• the ability to expand the scene easily
• there should be some color options for the lines representing connections between events
• easily shareing the idea with one another
• it's much more better to have a WYSIWYG editor
• easily explore in the large scene of events

in the end if you know any application which could let me create a board just like the one in my sample picture and share it whith other freinds it could help us a lot.
