Cool clocks

Where do you get the neon rings? Are you making them yourself or buying them? Last question how do you power them?
Keep up the pics!!!
The clock mechanism, neon tubes, and inverter for the neon for this one came from a *gasp Snap-On dual-tube neon clock that was given to the shop by our Snap-On guy. We weren't going to use a Snap-On clock in the car audio shop and when I started making a shop clock we pulled the Snap-On clock from storage to cannibalize for parts.
The joke was made the other day that, since this clock is being made from a 12" woofer it's always "twelve o'clock".
And then there was question as to whether or not I was on the clock. At the time I was literally working on this clock so one of the guys said "Of course you're working 'on the clock'". That one took a second or two to process.
I'll get more pics as I progress.
