After months of just idly playing with it, I finally got the courage to scramble my hexaminx from Traiphum's last batch.
It was quite gruelling due to the weird shape shifting and also because I coultn't remember how I solved the megaminx! But ultimately it was really good fun. SuperAntonioVivaldi recently mentioned a giga hexaminx (cube puzzle based on a gigaminx) - he got one from Binter puzzles on Shapeways. Now apart from the fact that I will never be allowed to dye my own puzzles, the Gigahexaminx is not on Shapeways any more!
Does anyone know if one is available any other way? I really enjoyed the "little" one and fancy a bigger challenge!
