Providing an function version of `&&` let's you use that function in more FP (functional programming) contexts, e.g. a data transform that does multiple map/apply/reduce transforms to a data set.
I had a lot of fun a number of years ago coding similar visualizations using processing. Turns out making each pixel a distinct object with it's only rules and behaviors is really fun!

Personally, I have found clipboard (http://clipboard.com) to be far better for saving things from around the web.
Their bookmarklet lets you clip an arbitrary region of a webpage, AND IT ACTUALLY PRESERVES THE DOM OF THAT REGION. That's right, it's not a screenshot. The dom of what you clipped is preserved, searchable, selectable, styleable, the works.
I have found that I can visually retrieve the clipping by quickly scanning my entire clipping collection in one scroll. It's nuts.
No, I do not work for clipboard, but I do use it for all of the following:
- Saving solid guitar tabs that I've found around the web.
- Bookmarking photoshop and illustrator tutorials, using the best graphic from the tutorial as the clipping
- Recipes, which usually consist of text and images
- Random awesome images
- Slideshare presentations (which can actually be watched from within the clipping
They're bookmarklet is totally magic sauce. You gotta try it out.
