What to do with 60+ glass bricks?!

lorrainbow

Hey folks,

I saw these glass bricks on Facebook marketplace and just had to have them!
Facebook post selling 70 retro glass blocks/wall bricks with phot
It turned out the person selling them is a friend whose website I updated lately so she was happy to give them to me for free! There's about 68 of them. They're covered in expanding foam and paint. I've started to clean them up using a scraper and some nail polish remover for the tough bits.

But the question is - what to do with them!?! They're 19*19*8cm. They're hollow in the middle so not too heavy. 
I'm going to get 9 cleaned up and stack them in a grid and light up the centre one from different angles. I want to see what's the best way to light them up. And then.... ??
  • A giant wall for Tetris? 
  • An igloo? (Thanks for the idea  !)
Also, how do I stack them? And where! I don't want them to fall on anyone but I also don't want to permanently stick them together. So a frame of sorts? It feels like an outdoor display to me.. so how do I waterproof the electronics?
Any ideas are welcome!

    Not necessarily a problem. ( If you drop one, then you will have an even number... Slight smile )

    7x7 would require 49.

    5x5 would require 25.

    3x3 would require 9.

    Lots of other non-square combinations will result in odd numbers as well.

    I suspect getting additional blocks would be quite easy as well.

    7 frequency bands so that works out well for rainbows as well...

    7x8 matrix = 56 blocks

    7x9 matrix = 63 blocks

    Odd number might work out better as you can do a centre zero stereo mode with left channel up and right channel down.
