Alternative title: Look! I made a thing!

The recent Formic Functions challenge was a lot of fun, and seems to have taken the concept of easy-to-run online javascript-based king-of-the-hill challenges to a new level. It's inspired me to make a framework for building them, which I invite people to take a look at!


(I have a vague idea for a KoTH challenge of my own, which I plan to build with this framework)

For those saying "wait, haven't we seen this before?": I for one think that the ease of just visiting a website and typing in some code gives this new style a much lower bar-to-entry for competitors, and the ability to develop games without any setup whatsoever (you can literally download the code and open the html files) gives a much lower bar-to-entry for contest writers.

My Question

I've been cloning past challenges to drive out the functionality, but so far I've only found 3:

There must be others out there. Does anybody remember any?

    \$\begingroup\$ @cairdcoinheringaahing I had the same concern, but there are some not-too-old questions here in the same vein, so I thought I'd risk it. Also I wanted this to be a bit of a collection of javascript-based challenges, which I think meta can do better than chat. \$\endgroup\$

    \$\begingroup\$ @FrenzyLi sounds fair. davidje13.github.io/koth-webplayer/formic.htm#screensaver (use with your choice of website-as-screensaver program). Wouldn't recommend leaving it on for too long though; probably not good for your electricity bill! \$\endgroup\$

  • \$\begingroup\$ Wha? huh. When I tried doing that I just got a bunch of answers for KoTH challenges which happened to be written in Javascript. This looks much better! I'll slip away in shame now… (thanks; I'll get cloning!) \$\endgroup\$

    \$\begingroup\$ @Dave The difference is that that request searches only questions. You can get similar functionality from the search box by using is:q. \$\endgroup\$
