I found the original Spheretta-5,7 while looking for "dotty" fonts, to make sure that the font I'm doodling at the moment will look a little different from others on FontStruct. I liked Spheretta and as cloning was allowed by the creator I made some changes as Meek's many innovations enrich our creative thinking **smile**  The original font was created in 2011 by arseniiv.

I smoothed the circle, worked into existing glyphs where I thought 'necessary' (nudges, ~re~moved some dots in glyphs or added dots to reduce some gaps).

Comparing parent and clone: changes are a smoother circle, a few symbols, the Lower Case for Basic Latin and most Latin1 positions,  some operators/symbols are available with as well as without the UC circle. And that I have broken the 5x7 rule in some glyphs to improve their lines.

In the LC glyph style (no circle) you have: full stop, comma, all quotation marks on Basic Latin and Latin1, apostrophe, asterisk, plus, minus, solidus, colon, semicolon, percentage, less, more.

The low line is a blank circle; decorative dot arrangements inside a circle are on the tilde, left square bracket, grave accent.

The original (with a circle) can be found here: the "?" is on "{",   the "!" on "}",   the "-" on "reverse solidus,   the "=" on "]"

I've added arseniiv's name and this parent-Fontstruction's year of creation  on the first letter of the  ""Even More Latin"" band, then added mine on the second letter on the same band.  Feel free to add more glyphs (and your name and creation year, following ours), arseniiv allowed cloning so that we can add to his work. I follow his idea; and like him I, too, can't find enough time to continue working on Spheretta-5,7 for the next months.   It would be great to see Spheretta-5,7 grow some more ...
