Fun Chromatic Challenge

Loving this puzzle! TBH not done yet, but really enjoying the quality of the pieces. Mostly the dichroic coating has me wishing I had a big lazy suzan to put this on and spin it to see the shifting colors. For an extra challenge I have been working on it under multi color led lights.

Challenging and Fun

I just completed this with my brother. The pieces are thick and a nice quality. It seemed daunting in the first session but the novelty of it kept us interested and we got better at it going forward. It took 7 - 8 hours to complete between the two of us and looked amazing at the end. Definitely worth a purchase.
