As to the procurement of CDs, don't worry bout that, we can get 100 for about e20 online, or 500 for about 65 plus shipping. I'm not sure how BIG we want to make it - so i don't know if 500 is too many or 100 too few. Also 200 is available. I think we'll go thru them quicker than we'd expect, so I'm thinking 200 at the mo.
Chainmail CD fish, that's the image I have. Upside down higgledy pig.
We could twist coat hangers and chicken wire into a fish shape, then cover it with CDs I lift my wand and wave you From hill to hill of delight. My rosy rivers lave you In innermost lustral light.
