How Could Google's New Logo Be Only 305 Bytes When Its Old Logo Was 14,000 Bytes?
The old logo uses a complicated serif font which can only be created using bezier curves. All together, it has 100 anchor points, resulting in a 6 KB (6,380 bytes) file.

A simplified version of the new logo, on the other hand, can be constructed almost entirely from circles and rectangles (with the exception of the lower-case g): The enti

Capabilities include layers, events, drag-and-drop, animation, and much more. The result is a flexible API wrapped up in a sugary, jQuery-esque syntax that brings power and ease to the HTML5 c
