11 shapes! This is a fun game. I think it's testing something other than shape rotating though.

#62Earlier quoted context omitted.
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.

#6312 matches on my first go. Not very impressive, but likely an indicator of my middling IQ.
That's impressive to me. I got 4 on my first go, 6 on my second and I doubt I'll be going much higher without significant practice. I find it extremely hard and made several wrong atttempts in addition to being slow.

#64Wordcels can’t cope with this.
Re: Show HN: Test your shape rotation skills
#65This is brilliant! (Especially after the rotating puzzle post yesterday, exactly what I needed!) Thank you! (I managed to get 14 at 8 seconds but damn this is pretty hard) feedback: Sometimes the shapes get too occluded by it's own body. Not sure bug or a feature. Also could be fun to increasing or decreasing difficulty curve depending on performance
Can someone post that rotating puzzle post from yesterday? I think I missed it (and can't seem to find by searching)

#66I’d be really curious to collect gender before testing, because I feel like this is always one of those go to examples of the difference and male and female brains, would be curious to know if there is any substantial actual difference.

#67Curious about group theory take on this. It seems that symmetry helps to easily exclude multiple shapes at the beginning of each round.

Difficult to control for the effects of "building toys" such as Lego being primarily marketed at boys. These types of toys help train this kind of spacial awareness from an early age.
See also early computers being marketed almost exclusively at men and boys, potentially being the cause of a major drop off of women in computer sciences in the 1980s: https://www.npr.org/sections/money/2014/10/21/357629765/when...
Re: Show HN: Test your shape rotation skills
#69I would suggest also adding some sort of error counting into the mix (perhaps allowing 3-5 lives in total, maybe with bonus lives if you're fast or you get it on the first try). Right now it's a bit too easy to semi-brute force shapes that are somewhat similar.
It would also be good to have increasing levels of difficulty. Eventually you could add a leaderboard.
As a side note, it's fun to see the amount of humble-bragging going on in the thread right now ;))

#70Finally, that semester of topology has paid out.
