Demonstration of Forced Perspective

I found two excellent demonstration videos of forced perspective recently. 

The first one is by Richard Wiseman . He demonstrated how to use optical illusion to make objects appear smaller or larger than they actually are. Photographers also use this trick to create context in their photos. See What makes a creative photograph for some examples.

The second one comes from Brusspup. I like the way that he showed camera zooming in before revealing the truth. Apparently, seeing is not believing.


  • Richard's website has a lot of interesting videos, e.g., bets you always win, that you don't want to miss!

The Deep Learning Saga

This is a hilarious video presented at the NIPS'2010 workshops banquet for the Deep Learning and Unsupervised Feature Learning workshop. Deep learning has drawn great attention in recent year in the machine learning community as well as other areas such as computer vision and speech recognition. This video gave a nice overview of the development in the area.
