Playing with Wolfram Playing Cards
- pavel_lishin 9y agoHow plausible are animated versions of these in real life? What's the thinnest we can make a display+processor combo that can be powered by, say, the heat from my hands?
- kaffeemitsahne 9y agoIt could certainly be done with lenticular printing (to some extent...)
- gh02t 9y agoI don't think you could practically power a display + processor combo with the heat from your hands. The best I can find on the power radiated by your hands is this article https://www.smithsonianmag.com/innovation/this-flashlight-is-powered-by-the-touch-of-your-hand-180950226/ https://www.smithsonianmag.com/innovation/this-flashlight-is... That article says you can get about 5 milliwatts using a Peltier converter, so working backwards based on Peltier converters being ~10% efficient that's only 50 milliwatts radiated by your hands. Even with an ideal 100% efficient converter that turns 100% of that energy into electricity, combined with a 100% efficient step up converter to raise the voltage that's not a lot to work with, that's barely enough power to light a couple of blue LEDs, much less a display and a microcontroller capable of rendering 3D graphics.
- anigbrowl 9y agoWhat if it's just a display plus a wireless receiver? SMartphones have not shrunk much over the last decade but that's cause of the constant pursuit of more functionality. I'd be quite interested to see how minimal they could go. I'll bet on playing card-size active displays within 10 years.
- sushisource 9y agoThose are really neat. I did say "of course" sarcastically out loud when I got to the King.
- Adrock 9y agoYeah, I lost it at that one. I'm not sure if that's his doing or just an internal troll.
- tehsauce 9y agoThe code for these is really short and elegant! Keep in mind when you want to make some graphics that aren't owned by the "king", the much more powerful (though some boilerplate is required) open source libraries like p5.js and three.js are capable of rendering these real-time in the browser!
- cprecioso 9y agoDid you mean D3 instead of three.js?
- ukoki 9y agoPrice: £4 — great! Shipping: £12 — nope!

- tsomctl 9y agoI'm always amazed by how expressive Mathematica is. Writing some of these expressions imperatively would be significantly more than one line.
- fjsolwmv 9y agoThese are mostly just API calls with arguments, with some simple lambdas. You can implement that in any language.
- maliker 9y agoI think the magic of Mathematica is the combination of (1) a huge collection of well-maintained CAS and math functions (2) great graphics and animation support (3) the notebook interface (which jupyter is catching up on fast) and (4) some of the best documentation in the industry. Modifying the Mathematica code after its written, however, is very tricky.
- sizzzzlerz 9y agoWhat you said plus the accuracy and precision to which results are computed. They're effectively limited only by the amount memory you have and your patience. And even patience isn't required unless you're calculating pi to trillions of digits. It's really fast.
- blt 9y agoEven if some of the components in Mathematica are not state-of-the-art, there's a huge synergy benefit from having everything together in one environment, using the same datatypes. I think that's the big benefit of Mathematica and Matlab. Python can match (or exceed) a lot of their capabilities but you spend all this time with package managers, converting data types, etc.
- brianwawok 9y agoWhat is this time with package managers? Takes an hour one time to learn pip and virtualenv. Then its 1 pip command to install a package.
- m00s3 9y agoCool cards. What's not cool is $50 shipping on $5 cards. To Canada...
- ninju 9y agoThey should provide a QR code on each card that sends you to the Wolfram site with the expression being executed, that way when you are waiting your turn on Hold-em you can watch the animation from your phone (it must have been a pain to hand type those expressions...great job!)
- tunesmith 9y agoThe seven of clubs actually vaguely frightened me. What an appetite.
- hackpert 9y agoIndeed, of all the tech company swag I've seen and collected, from a pure nerdiness metric, I'd wager Wolfram's remains one of the coolest by far.
- zitterbewegung 9y agoA CAS with beautiful graphing is a big feature that is required in most situations and their swag wants to sell that point .
- godelski 9y agoIf the OP is here, I found the cup on their site. It lets me put it in my cart http://store.wolfram.com/view/misc/index.str#heart-spikey-mug http://store.wolfram.com/view/misc/index.str#heart-spikey-mu...
