The shapes were not drawn by hand. The official notes describe the collection as generated by a script from the open Rubik family, with the generating code published separately, and Rubik Bubbles is one of several filtered variants. Underneath the effect the proportions are those of a wide, very bold sans with rounded corners. The font has one style, Regular, and 774 glyphs spanning Latin, Latin Extended, Cyrillic and Hebrew. NaN and Luke Prowse are credited as designers, and the font's name table also lists Hubert and Fischer, the studio behind the original Rubik. ## License SIL Open Font License 1.1.

Other effects in the same generated collection are separate families. - **Detail needs size**: The bubble outline is made of small circles and narrow counters, drawn to be seen at display sizes. - **Generated from Rubik**: The outlines were produced by code applied to the Rubik family; they were not drawn letter by letter. ## FAQs ### Is Rubik Bubbles free for commercial use?
