And the worst thing is they don't use a piston array! Making a scrolling wall of blocks is fairly easy within Minecraft and would've saved them the trouble of manually shifting all their blocks every single frame. That's easily an order of magnitude less work, and can be re-used for other stop-motion movies.

Their excuse? "We dont have the smarts"(sic). Sigh.

Pistons can only push rows of 12 blocks; the Game Boy screen is much wider than that. I can imagine building a system to push groups of 12 separately without any exposed mechanism when idle, but I think that is likely to be impossible.

You could divide the screen into rows 12 blocks wide, each powered by an array, with a 2 block gap. You put the arrays one level below the display level and push the blocks up (via sticky pistons) each turn. You'd still have to manually fill in the gaps, but that's only 22 out of 160 lines.

You can combine the arrays like a big stair and only have a 1 block gap, but that requires some manual working of the pistons each turn (because you can't hide the wiring). Not sure if it's worth it. I'm 30% confident it can be automated without exposed wiring.

I have been thinking about a gapless way on-and-off over the last 2 days. I don't have one yet, but I'm 70% confident I can figure one out without the help of the r/redstone hivemind in less than 50 hours of thinking. I've put building a working implementation on my Minecraft todo list. There's no way this is impossible.

... and I've build a working prototype. Took about 3 hours to figure it out, 2 hours to get the wiring to work (first big redstone project), another 1-2 hours for the array and timing. It's trivial to scale and can be easily extended to push in both directions. The whole mechanism is hidden. I think there is a delay of ~8 seconds per 12 blocks, so scrolling the gameboy screen should take ~1.5 minutes. I'm sure you can get this below 1 minute if you try.

Here's the video. Here's the save. Here's a bunch of screenshots instead of a blueprint or explanation.

...why we can get people to do this but not our open volunteer tasks...

Volunteer tasks? I wasn't aware you (I'm assuming that means Less Wrong or SIAI) had any; perhaps you have a visibility problem?

Or maybe they're just not as engaging as an open-ended engineering environment with no arbitrary entry requirements and no visible resource constraints. . .

http://www.singularityvolunteers.org/opportunities Less engaging and visible, yes. I was going to quote http://lesswrong.com/lw/h3/superstimuli_and_the_collapse_of_western/ back at Eliezer, but I don't think he's actually surprised, just lamenting the phenomenon.

What effort have you applied to making your volunteer tasks this catchy and rewarding?

Some exposed mechanism seems okay; it works for LCD displays (and some older ones had a pronounced screen-door effect). You could scale it up, but it is an unfortunate fact about Minecraft that mechanisms far away have no effect.

So it is a fail in both effectiveness and efficiency. http://www.ted.com/talks/tim_ferriss_smash_fear_learn_anything.html
