small update in what i have done, huge one in meaning :)
pretty much what i did: got some plexiglass and frosted it. i frosted it by using 400 grit sand paper and a automatic sander. it worked amazingly well as you will see. i also clear coated the burnt parts, but thats to keep a mess from happening, and to almost freaze the charred where it is. enjoy :D

worlds best glue drying mechanism ever

if you cant tell, thats a brick of clay. my dad likes to do pottery in his free time, and that stuff is DENSE

there is something under there.. ;)

hehe now i get to wait 12 hours for the glue to dry =.=

o...m....g..

this is perfect...the frosted just filters the light, letting it almost glow. perfect for me :D

the back side. all those spots are just where i glued. but thats also the frosted look i got with the 400 grit sand paper

:D
anyway, hope you enjoy, and comments welcome :) thats how ive gotten a few of my ideas, at least the flame one, are from comments (someone gave me the flame idea but i cant remember who sorry)
