Here's my rough photoshop concepts
Front and Side with the Plug
I have it a look to make it seem like an extension of the pack (similar colors, ribs, and light bars.)
Afterwards, idealy, I thought another set of switches might be needed, or somehow isolating the lights in the gizmo itself - so that it could either:
A - turn out without affecting the pack, so the gizmo would run by itself.
B- a second connection inside would be linked directly with the pack itself, in case I wanted to turn on the pack alone without using the wand. This would also be helpful if I wanted to do some kind of alternate GB costume and wasn't using my wand.
The plan is also to have this detachable like I plan to make my hose, so it can be an optional attached to my pack, or if I want, attached to the belt somewhere.
