what can i do with 5mm glass??

[Reef Puffer]

so i decided to just build it. hex 20 1/2"w by 18"h (like 85gal or so). will see what happens... photo bucket still wont work for me? but i attached a photo of my build just to give an idea of what im building here (just cut and placed glass with tape). keep in mind i'll beef up the stand and build a skirt around it, aswell as some sort of large hex hood. thanx for playing along, if anyone is interested just lemme know and i'll keep u posted on the progress. not sure if it will be a temporary home for my id sharks then build a sump and overflow for a reef. or just leave it planted FW for the sharks and find some small rays and discus maybe? thanx again for all your inputs, and i wont hold anyone liable if this thing blows out!!
