Pretty Cool, Now I know what Format symbols are. Also, does all of the presets I uploaded on this site are all made in Format 3? There's also a Format 4 shown in this page which said that it will be the future version of Caustic such as 3.3 or 4. And I also saw that you have 4 green symbols which also use for the first 3 versions of the Caustic app. Anyways, how did you come up with the colours for the format symbols for Caustic and what makes you numbers the Format based on the version of Caustic?
RHOMBUS ARE AWESOME!
