Dipity:
Dipity is a former program of the Cloud Computing philosophy. It`s a tool which lets us create and visualise timelines created by users from ditity whithout the necessity of installing any kind of software in our computer, so wherever you are, whatever computer you are using, you can always search and see the same timeline.
If you create an account you can also create and comment other users' timelines.
There are only two kinds of dipity account: The free version and the premium.
With premium you get more palets and backgrounds for your timelines.
