I'm the author and I submitted it last night, not sure how it went through the repost filter. <a href="http://news.ycombinator.com/item?id=3503758" rel="nofollow">http://news.ycombinator.com/item?id=3503758</a> but glad to see it again.<p>In addition to d3.js and Raphael, it uses an implementation of L<i>a</i>b for D3 by Jeffrey Heer <a href="https://github.com/mbostock/d3/pull/183" rel="nofollow">https://github.com/mbostock/d3/pull/183</a>, and the colorblind implementation uses superformulas for D3 by Christophe Viau <a href="http://bl.ocks.org/1020902" rel="nofollow">http://bl.ocks.org/1020902</a>
This is really impressive and well made. Love the design and UI in addition to the game just being fun. You can see how much thought went into it when you see how the scores are presented after you completed the game.
At first glance my reaction was "Wow, what a pivot! I wonder if their VC's are pissed yet and want their 40 million back yet?" :)<p>But anyway, very cool. I'm loving watching all the interesting projects using d3 lately.
Very nice!<p>The only complaint I have is that I kept on associating the position of my mouse with a particular circle or segment. Then sometimes nothing would behave like I expected, and I would then spend a significant amount of time trying to figure out which circle to associate with which segment. It didn't seem to me that this is really part of the 'gameplay', it felt more like trying to figure out which keys to use for a new game... but then for every level.<p>It's hard to say without actually trying it, but I <i>think</i> having the internal segments 'follow' their respective circles would have been much more intuitive for me.
Ended up with 1 "Poor", several "Perfects" and mostly "Very Good" and an 8.7 overall score. Very addictive game and well put together. I may have overlooked, but is the source available? I probably should of just checked "View Source".
Great work. I've already been more fulfilled with this than I have with the multimillion dollar Color startup...<p>It'd be cool to see the actual deviation in numbers...I feel that some of my "perfect" matches were just shots in the dark.
That was fun. One thing I'd suggest is previewing the new widget during the countdown to a new test, the two dimensional transition to saturation threw me off a bit as my brain came to grips with the new representation.
Very neat, though I've noticed that I can get 'perfect's while I can still see the difference... intentional?<p>Anyway, creepily addicting once you start :D Great job in every way.
Good job. It is kind of addicting.
I think a point system that depends upon the degree of color match along with time taken, will make it even more interesting.
