Bunkr has been around for a few years. However, they very recently Re-built themselves from the ground up. The streamlined tools and formatting will not appeal to those who are heavy powerpoint wingding/clipart/rainbow-font graphic users. It's a very minimalistic design. Which I respect, because presentations should focus on what the presenter is saying and slides should reinforce what is being spoken. Infact, I uploaded on of our graphic-heavy canned presentations and Bunkr essentially imported them as jpegs.
Instead, Bunkr focuses on web-data; stuff already on the web. Yes, it's cloud-based. No, you cannot download a presentation. No, there is not animation. Deal with it. You can however pull in Google Drive, Dropbox files, Instagram feeds, Pintrest boards, YouTube Videos, Grooveshark Playlists, Time/BBC/TechCrunch/Wikipedia Articles, images from anywhere, Code from Codepen ... and on... and on. Seriously, the current list is about 75 different online services and the application is still in beta. (You can open and read PDFs!)
Get to the Maps man!
At first I was excited to see the ability to embed code. That way I knew at least I could share a CodePen and display the results. I've played with that service before. Using it to keep, test and maintain good iFrames of embedded maps from our ArcGIS Online. In the example Bunkr presentation below, the first map is this CodePen. It works ~fine~ and the display isn't 'horrible'. Still, it is using another service to 'host' your iFrame, so there is some funkiness there, not everything displays exactly like you want.
Then I Learned that to display the Google Drive document, Bunkr requests the iFrame code directly. So, I tried the next logical step and inserted the whole code snippet from my shared ArcGIS Online map. BOOM! Complete slippy map in a presentation format. Here is the presentation to truly understand what I mean.
