Set 3
Comments:
Second set from WCW
Most comments liked 5 and 6 (although Tim still holds out for 1).
We need a general logo not just a uP4 logo. Option 3 looked attractive without the version number.
There is a desire to have the logo be more contemporary and compelling. Perhaps enhancing the 3D look.
Adding a 3D ball might add interest.
Perhaps something else could be added that conveys interconnectedness.
Maybe add a 4 to the current logo.
