Jux is a new service that I just found out about that allows you to create and share presentations in a new way. You can add images and text very easily and add effects to create the impact and emphasis you want. It showcases your presentation fullscreen on desktop, iPad, iPhone and more platforms are coming.
Photos are shown at full resolution, you can add videos, write text over photos as backgrounds, and even create some great lists using it.
It is free, but requires you to create a login account.
This is a new way to create stunning presentations. Students and educators can both use it.
