Electric Slide is the easiest way to wirelessly present PowerPoint slides, Office documents, PDFs and videos with your iPhone or iPad. Your device is a remote control that works anywhere with any screen. Since viewers just need your simple URL to follow along, setup is a cinch. You can also connect your device directly to a TV or projector via HDMI or VGA.
This is the presentation tool we just heard about today in our opening meeting at Penn. In short this app allows you to control a presentation by uploading to electricslide.net and then by choosing to "broadcast" your presentation it allows your to share it. This is similar to Splashtop for iPad but the advantage is that anyone with your "room number" log in can watch the presentation on their personal device. This can happen even remotely.
