Small bug: occasionally there are multiple matching pairs, although only 1 works (screenshot: https://ibb.co/JpRp0Pm ) Additionally, the auto rotation itself is mostly confusing, could be better to enable manual mouse rotation. Cool game nonetheless! Edit: The bug seems to be that shapes with different "DNA" can still be isometric in some cases: https://github.com/0xf00ff00f/rotator/blob/master/demo.cc#L4...

I encountered the same bug and it was also a donut kind of shape, maybe something to do with the closing of the loop?

Probably. L-U-R-D is the mirror of R-D-L-U but not the mirror of L-D-R-U, although isometric to both.

Pretty weird, the first two are consistently way harder for me! They take 20+ seconds each, and then the subsequent ones take only 3-7 seconds. In my third try I managed 14 shapes, 8.33 seconds per shape, on my first I did 7 - it's pretty clear that you can train yourself to get a lot better.

Also, once, there were two matching pairs, but only one was accepted, I'm pretty sure.

Scored 7 my first go but that was aided by one or two that were more or less had the same orientation and could spotted pretty easily.

I thought I'd be good at this since I do 3D editing all day, but apparently not. In my first try I couldn't get even one. Practicing some more I got up to 4 in a game. I wonder if this game can distinguish between people who have rich mental imagery and those who don't?

You might have too rich of a mental geometry framework such that each shape was rendered more thoroughly, but not necessarily in a way that helped compute matching objects.

Ouch. Thank you so much for noticing this! Looks like I need a more robust test.

Ismorphism is hard to detect, even in reduced spaces. Really hard in arbitrary graphs.

For a "fast filter" generate the center of gravity for each (just the average of the voxel points as doubles) and abs+sort the resulting vector and assume they match if the "Sorted Cog Vector" matches. It will have false positives sometimes but no false negatives.

I'm amazed that some people can actually rotate objects.

On of the reasons I don't drive is for fear of driving directly into traffic, if I make a mistake figuring on which lane is "on the right side" of the new perspective when turning.

Mental rotation is one of the very top causes of mistakes for me and I've learned to always be on the lookout for it, and assume my conclusion is wrong if I find myself doing it.

Waiting out for the wordcel version of this

You mean Wordle?

It's a 4chan meme: https://knowyourmeme.com/memes/cultures/wordcel-shape-rotato...

So this game going to the top of HN is likely part of the meme where shape rotators strike back against wordcels after wordle became popular, something like that.

Damn, that's surprisingly difficult. But I think I shouldn't be allowed to brute-force answers (that's really tempting in the current design) and I'd probably appreciate if shapes were standing still, since the movement is distracting and barely relates to the skill being tested.

-10 seconds if you fail a pair should work against brute force.

Maybe an advanced mode where extra seconds are deducted for each wrong pair guessed? And along with that the ability to skip a turn for extra seconds deducted. That way, since brute force would no longer be an option, you wouldn't find yourself getting hopelessly stuck early on behind a particularly difficult set.

It's actually a Twitter meme by @tszzl on Twitter. It was a 4-chan meme to add "-cel" to words, but the shape rotator vs wordcel meme is from Twitter.

That's a lot of fun, I'm sure pmarca loves it :-). Initial rotation can result in feature hiding that is critical, perhaps making the wobble selectable (easy = big wobble, medium = current wobble, hard = no wobble) The follow on should be the folding one (planar surface with dotted lines, pick the folded version) I always thought those questions in IQ tests were put there so that there would be some "easy" questions that everyone got right, but found later my wife couldn't do them!
