Quoted from Timelord000:
I'm interested in seeing that plasma disk in action. It doesn't look like just a cheapie toy plasma ball.
We have been making plasma pop bumpers for 2 years, they look great and have a long life. They are a bit taller then standard pop bumpers, but fit in many games. This google search has different levels of prototype, installation instructions, how they are made and installed in some games:
If you want put a mod in your game that is the first thing people will see, plasma pop bumpers are what you want.
The core that we start with is not that expensive, but we have to do a huge amount of work for the mount, controls, colorizing, protecting the glass and so on.
We have been selling as we get requests.
