This reminds me of that. It's charming. | dajonker wrote: | This is fun and had a high potential for giving me some | repetitive strain injury. My highest score of 97.1 doesn't | visually feel like the best circle I've drawn though. | mgdlbp wrote: | Its ideal circle is centred on the dot | Tevias wrote: | Also interesting to try to get low percentages. Worst I could get | was 53.1% by drawing a rectangle over my whole screen. | FranchuFranchu wrote: | I got 20% by drawing an ellipse | bmacho wrote: | I got 2.6 for starting close, then circling a big circle, | like this https://pasteboard.co/vYFY7MSrgcoD.png | mgdlbp wrote: | 2.7% by starting the rectangle close to the dot (it measures | deviation from the initial radius) | hnkimo wrote: | Try to keep the radius as small as it lets you. Move very slowly, | you'll likely be too slowly the first few tries but find the | slowest speed possible. I got 97.3% with a mouse doing this. | sam33r wrote: | This was fun! It seems like the faster I go, the better the | median score gets. My finger on a phone beat my vertical mouse | (as I expected), but not by much: 95.8% vs 93.5%. | stjo wrote: | An even better challenge: try to draw the least circle-like | thing. It is surprisingly hard! | tomovo wrote: | A nice square gets me 77%. Good enough for me. | scandox wrote: | Thumbs superior for some reason | chairmanwow1 wrote: | Drawing a triangle resulted in a score of 77.9? | alexmolas wrote: | Supercool!! it would be nice to see how do you rank with respect | to other users, and see your percentile. | martyvis wrote: | Fun, but needs more rewards than just a high score. Maybe | something like a consecutive streak above 90%? Or a challenge | where you need to target a given radius. Anyway, nice job. | | (I recall how my senior hugh school maths teacher was wizz at | drawing circles, lines and other geometry on the chalkboard) | yabones wrote: | This is basically impossible with a trackball mouse :) | zamadatix wrote: | As a tip: what it's really checking is for a circle centered on | the dot in the middle with the radius equal to your initial | click's distance from the center. You could make a mid sized | perfect circle which is slightly off the center of the dot and | lose to a square that fills the play area. | [deleted] | pstorm wrote: | I was wondering why some circles seemed great but got low | scores. To test your tip, I just made a square and got 92% | dxbydt wrote: | My anticlockwise circles score more than my clockwise ones. | Is there some theory behind that ? | fishtoaster wrote: | I've managed to get 97%, but only by busting out my ipad and | using the stylus. A fun little game! | blank_fan_pill wrote: | All these little apps are really impressive from a web | development point of view. Shows a real mastery of css, canvas, | browser apis, JS, etc. Kudos. | ynfnehf wrote: | By cheating with a Python script to move the mouse, I managed to | get 99.9%. Seems difficult to get higher than that, perhaps due | to the mouse position having integer coordinates. | dmix wrote: | A mac or windows app controlling the mouse I presume? | majkinetor wrote: | I literray came here to see who is going to proclaim automation | first (and in what way) :) Unsurprinsingly, it was the first | comment. | | 100% perfect circle is a pure math thing and can't be achieved | with drawing in any way. | limaoscarjuliet wrote: | Surprisingly entertaining! | dxbydt wrote: | Hey this is so well done! You know, you could put the sun on one | of the the two focii and ask the user to draw the elliptical | orbit of the earth - perfect real-life usecase. | michael9k wrote: | Cool. Actually harder than I thought | ehsankia wrote: | Another great neal.fun page. One feature I'd like to see is, make | the user to N circles in a row and take the median score or | something. Right now you can just spam hundreds and take your top | score, but it doesn't really reward consistency. | majkinetor wrote: | Yeah, we all totally need consistency reward. The game will | become borring without it :) | gerdesj wrote: | One of my maths teachers was able to draw up to something like a | three foot circle on the blackboard that looked very, very close | to ideal every time. He would always use two arcs to do it and it | was uncanny. He would whip out a metre/yard rule to do straight | lines because they are much harder to do. | | Your limbs etc are all a collection of ball and socket/downright | weirdly jointed/hinges with benefits/more weirdness. You then | want to use this monstrose agglomeration (did I mention how you | move the bloody things?) to draw a circle? Obviously you would | decide to run a finger over a simulator of a lump with a ball in | it and some on/off switches. | | People are weird. Nice website though. ___________________________________________________________________ (page generated 2023-01-06 23:00 UTC)
