Roundle kept a shoebox, and inside the shoebox lived a family — though to a stranger it looked like a jumble of the exact same little wedge, over and over, tilted a hundred ways.
"Why do you have so many copies of one block?" a builder asked him once.
"They're not copies," Roundle said, beaming. "They're one wedge, sitting every way it can sit. Watch." He tipped the wedge onto its flat, then its point, then its long edge, spinning it a quarter here and a half there, and each new pose he lined up in a proud little row. When he finally ran out of genuinely-new poses, he counted the row. "Twenty-four. That's the whole family. One little wedge has exactly twenty-four different ways to stand in the world, and not one more."
The builders thought this was a funny thing to be excited about, until the day two of them nearly came to blows.
"This shape is mine!" said the first, holding up a green corkscrew.
"No, THIS one is mine," said the second, holding up a green corkscrew that faced a completely different way, "and yours is a knock-off!"
They shoved the two shapes at Roundle, both certain the other was lying. Roundle didn't take sides. He simply took the first corkscrew and began to turn it — tip, roll, quarter, tip — walking it through pose after pose from its family of twenty-four. On the eleventh pose, it dropped onto the second corkscrew exactly, edge for edge, cube for cube.
The builders went quiet.
"You were both right," Roundle said kindly. "It's one shape. You were each holding it a different way. See — I found the turn that lands one onto the other, so they were never two things to fight over. They were always the same, wearing two of its poses."
That is how Roundle settled every squabble in the workshop after that. He never argued about how a shape looked, because looks change with every turn. He only asked one calm question: is there a turn that lands one exactly onto the other? If yes, same shape, argument over. If no, then truly different, and worth talking about.
He closed his shoebox with a satisfied little pat. "Twenty-four poses, one shape," he said. "If you can turn one onto the other, they were always the same."
The VoxelForge ensemble
Roundle is one of the friends in VoxelForge. Each friend shows you one idea by how they act; meet them all and you have the whole subject.
-
Turnwick
Embodies rotation - turns a voxel shape through space so it lands in a new pose but stays the SAME shape (turn it, don't change it)
-
Twinn
Embodies the mirror image (chirality) - the flipped look-alike that no rotation can ever match, like your left hand and your right (a flip is not a turn)
-
Layla
Embodies layers (slices) - builds a 3-D shape one flat horizontal layer at a time, floor to roof, so a tall build is never scary
-
Cubbin
Embodies the voxel - the single unit cube placed at exactly one spot; every giant build is just single cubes, each in its right place
-
Fitwell
Embodies the match check - compares a build to the goal cube-for-cube and says 'matches' only when every block lands exactly (looks-close and matches are two different words)
