Mobile Slideshare
http://m.slideshare.com/ is a landing page on Slideshare for mobile phones. The resolution of each slide is reduced to 240 by 180 (still in horizontal mode). I noticed that slides with white backgrounds and sparse content did not always render properly (big black blocks on some slides obscuring the image, as if the writing was ‘missed’ and averaged when the slides were compressed). A slide deck with yellow as the background colour worked fine (in my Web browser on the laptop, not on a real phone).
As you can see, writing is reduced even further in size so we are looking at a few words per slide and very crude diagrams. Interesting way of getting content onto mobile devices though…
