Corvis (temp bot name) rough ideas.

[james...venom]

If you have the technical ability to create it that's great. Its really good to see some different designs and thinking outside the box. As an event organiser, if you could send some technical drawings of how the projectile will be tethered and the mass of the object being fired we can make sure it is safe to contain in the arenas. It may well be if its anywhere near as effective as you suggest, and you seem to know what your talking about, we may want to arrange some testing of your machine at our workshop to be sure it's safe to contain inside the arenas
