I saw a few neat ones on my trip around Seattle and Bellevue last week.
First, a signal suspended from a wire:

In Bellevue, some signals have the symbols cutout and even centered:

The hanging peds reminds me of the ones I saw up in Nashville, TN.
Also, the bottom two signals use standard countdownless LEDs in them. The only major difference is that they don't have an eggcrate visor over them, which makes it easier to see the design of the LED.
I have seen both cutouts as well as the centered symbols in many places. Centered symbols were once common on early LED signals before countdown timers became the norm.
Nowadays most cities seem to like the "incandescent look" type signals, which places a diffuser (with or without an eggcrate visor) over the LEDs to give the symbols a more uniform appearance.
The suspended pedestrian signals are definitely interesting. They're few and far between.
If it was low enough, I wouldn't be able to resist the urge to high five the Don't Walk hand :-D
