Set 3
Comments:
Most comments liked 5 and 6 (although Tim still holds out for 1).
There is a desire to have the logo be more contemporary and compelling. Perhaps enhancing the 3D look.
JimH suggests a variation of 6 that makes the disc a 3D globe.
We need a general logo not just a uP4 logo.
Maybe add a 4 to the current logo.
Something with interconnectedness.
Maybe 3.
Other logo examples:
JimH couldn't find any.
