I was experimenting with incorporating a basic nuclear principle into GMod yesterday. Only, instead of plutonium I had to use barrels--and I was making a giant claymore. So, I guess that makes it kind of like a giant conventional explosives nuclear claymore of doom.
If you want to see the antics (I had problem after problem with controls and props), here's a four and a half minute video. I think it's worth it in the end, when it finally
does explode.
