Hi iMaterialise fans,
Professor Rocket is a higher-order version of Rocket Twist. Its core is the same as Rocket Twist, being held together with dovetail connections. The extra layer (cf 3x3x3 -> 5x5x5) was hung onto this core. Surprisingly, this puzzle was first-time right, as it is the first higher-order twisty puzzle with a hollow core. The puzzle has all the reorienting-in-space properties of Rocket Twist, with some additional interesting canonical shapes.
