Tumblr is one of the free platforms most I like because it is very customizable, it can be used as you really want, even from a blank html. I'm lately seeing several tumblrs which feature interesting themes. I just found this one by Thirozumi, to be honest in the beginning I didn't know what I was seeing, I only noticed about the colored diagonals and the cool visual effect by scrolling down or right. Then I went to its archive to see the single posts and what kind of content had there. On the archive there are normal pictures from reblogs or posts but if you click on whatever picture you go to a single colored diagonal, so this tumblr shows all the content published on in that diagonal and deformed way, I really like it, it's like two projects in one, a personal research and an abstract colored visualization from all that research.

It doesn't work using endless scrolling, to go to the next pages just click on the "next" link on the bottom left. The same to see the archive. http://thirozumi.tumblr.com/
I have looked at all the archive and I have found few GIFs, I was thinking how beautiful would be to see at least one page of this tumblr full of different animated GIFs. Like I just said before, when you click on a single picture on the archive you go to that picture seen as a diagonal form. I clicked on a classic GIF of dvdp and that is the cool view. See it here.
