... and do you have any plans to offer the design as a board or kit at any
time?

Very impressive - could we see some video of it in action?

The shield has a function of handling a static discharge when the plug is
attached or the board is touched. A conductive ring around the edge of the
PCB connected to the shield will prevent blowing out the electronics when
that spark occurs.
A resistor from shield to signal ground is reasonable.
If the USB device is powered thru the USB connector, you probably could get
away with tying the shield to the circuit ground. But if the USB device has
it's own supply, you definitely want resistance between the shield and
circuit ground to prevent ground-loop currents, which cause noise
Not a lot of help but from the USB spec:
6.8 USB Grounding
The shield must be terminated to the connector plug for completed
assemblies. The shield and chassis are
bonded together. The user selected grounding scheme for USB devices, and
cables must be consistent with
accepted industry practices
I don’t know, but thought I might point out that it appears you have the USB
connector running in line along the circuit board. Maybe you meant to do that
though.

I'm trying to make a CPU load indicator with 3 IN-12. This is my first
project using USB power and data from a PC
I'm not sure about the shield of the USB connector, Google is a little bit
confusing about this point...
Basically I found 3 different opinions:
1. Do not ground the shield
2.
That's a piece of art, great job!

Ian, may I ask why you've chosen to use LEDs for the colons with most of
your clocks? I think neon looks so much better.
