"Fixing" xkcd 1340 (or making the most redonkulous clock ever)

Update: feeling adventurous? Clone or fork the xkcd clock! If you just want to see it in action or get a glimpse of how it works, keep reading.

Problem

The date in xkcd's comic number 1340 does not change.

Solution

Since Randall publishes his comics under a permissive license, anyone can fix this problem and let the guy focus on more important issues, like writing great comics.

We propose the following approach:

1. Grab the original image and erase the date using a raster graphics editor, such as the GIMP.
2. Save the image to PNG and convert it to base 64.
3. Obtain the xkcd font and convert it to a web font using FontSquirrel's font-face generator. Select the "expert" mode and check "Base 64 encode."
4. Put all the parts together with HTML, CSS and Javascript, just like in the reference implementation

The results can be seen in http://jsfiddle.net/Lej6m/4/.

Overengineering the solution

In the spirit of the HTML clocks posted on HN, it is possible to make Cueball update its speech bubble every second, making http://jsfiddle.net/Lej6m/25/ the first instance of an xkcd-inspired clock that the author is aware of.

Conclusions

In this Gist, we have shown that it is possible to waste one's time to build an awesome clock using an xkcd comic strip as a clock face. The techniques shown in this work can be extended to other webcomics, or to newspaper comics that have been previously scanned.

I wonder how hard it would be to edit the font so all the digits have the same width... the clock bouncing around as the seconds change width is a bit distracting...

@christianbundy and @sloanesturz: thanks a lot! Your suggestions have been incorporated into http://jsfiddle.net/Lej6m/25/ .

1. This is a great idea, and very well implemented!
2. Thank you for pointing out that there is a good version of the XKCD font, I shall use it in my HTML port of Frequency (which is a good thing to look at if you're interested in other XKCD comics being HTML-ified.

@tomlof Yes! Do it!! Great idea!

@mrphlip fixed

If you use a subset of the letters of the font, namely "1234567890:- " then the css file becomes smaller. You can also make the png a lot smaller. See both changes here (nothing visibly changes, only the base64 strings):

http://jsfiddle.net/Lej6m/46/

Together this decreases the css file from 46kb to 16kb!!!1!11!

You inspired me to do a quick version of https://xkcd.com/now/ => http://meandavejustice.github.io/xkcd-now/

More clocks: http://xkcd.com/1335/

You can add a 1px dropshadow to the text to compensate for the weight and aliasing differences.

text-shadow: 0 0 1px rgba(0,0,0,0.25);

@tomlof and @DouglasLivingstone
Here's a couple shell scripts I wrote for 1335. The first gets the images, and the second gives the path to the correct image for the current time. I have a cron job running that uses the second script to get the image for my desktop wallpaper.

@hmottestad We could probably use canvas so that it's consistent on retina displays.
