I was too busy trying to think of one about some video game where once you become religiously powerful enough you activate a super-awesome Sabbath Mode. But a joke about modal metal music would probably be funnier.
Exactly. Some of the very Orthodox were just ignoring it and walking across at any time they wanted. Sometimes, this meant going across non-stopping traffic. Now, the lights turn red every so often, so that cross-traffic stops and people can walk across, without having to push the button.
AIUI solving a Rubik’s Cube is allowed on the sabbath. Rearranging the pieces of the cube through twisting and turning does not create a new object.
However, removing the stickers and then sticking them back on is forbidden. The act of applying a sticker to a surface is regarded as creating a new object.
Lately, I’ve been wondering about the use of certain medical devices on the sabbath. Clearly, if the device is necessary to live it is exempt. So you don’t need to turn of your pacemaker at sundown Friday. Presumably, using an electronic meter to read your blood sugar is permissible as well. But, what about hearing aids? They are not necessary to save life. Are they acceptable so long as you turn them on before sunset Friday and leave them on? What about machines that speak for people? Would Stephen Hawking have to say nothing on Sabbath if he were a Jew?
Is it too soon to point out that, traditionally here on the Dope, this question should have been asked on Friday, around sundown?
Interesting and thank you, but this begs the question is worship a creative activity.
They help you stay alive while you are walking to Shul through traffic, though.

No, because it’s purely within the spiritual realm. That which is forbidden on the Sabbath involves creative change to the physical world - i.e., the world that was created on the first six days, from which G-d rested on the seventh.
Way back in the 60s I drove a taxi part time in North London. Every Saturday I had a regular job that many of the other drivers refused to do on the grounds that it was too much trouble.
I would pick up an elderly Jewish couple from their home in Edgware and take them to visit her mother in Highgate (near the cemetery where Karl Marx is buried). On the way there I would stop and buy a bunch of flowers and a box of chocolates for the old lady. Later on I would collect them and take them home. They would not speak to me at all, and I got the instructions from the office in advance. Under no circumstances was I allowed to exceed the speed limit.
On Sunday I would call round and they would pay me the fare and for the flowers and chocs, together with a [fairly] generous tip.
Very interesting TY
What about the new light switch sensors, which use motion detectors to turn the lights on when someone comes into the room? The clearly use electrical ‘sparks’ to operate the sensor, and to trigger the lighting circuit. Must Jews who are observant of these silly taboos not use such light controls in their home?

t-bonham:
Yes, or at least have them set to stay on/off on Sabbath. In fact, we try to avoid triggering outdoor motion-triggered security lights if we know where they are and how to avoid triggering them.
You can’t have people slowing down for you, seems that would be a violation.
Stephan Hawking would have considerably less to say on any day if he were a Jew, but probably not because he couldn’t use his speech device.
Sorry - the range wasn’t delivered until Saturday, otherwise I would have posted the question sooner. 
Shall we start a thread on eruvim?
Briefly, you are not supposed to “carry” anything on Shabbos. Except indoors. So you take some reasonably large area put up (or more likely designating already existing) wires as enclosing a large “house”. In NY (which mostly forbids overhead electric wires) they have to be erected and there are groups of people, holier than though types, who tear them down. In my town they just designated a ring of wires enclosing the whole town. Despite the fact that this designation was entirely notional, there were protests by non-Jews.
My non-Jewish DIL worked for six years at Beth Israel hospital in NYC. The first time she encountered a Shabbos elevator, she thought she had wandered into a defective elevator until someone explained it to her.
I visited a family in Israel on Shabbos one April and about 4 in the afternoon, the house lights suddenly came on. They were on an automatic timer. A kind of electric shabbos goy.
I did not know that. You have again fought ignorance. 
Sabbath Mode is for cooking War Pigs.
How’s that? I got a million of em, I tell ya!
Thank you! I can’t tell you how many times I’ve looked for that!
What about flushing or using faucets?
Marketing ploy to get the Jewish dollar.
Yeah, I kinda thought of that one, and rejected it. There has to be something better.
It’s making me paranoid!!!
For cooking N.I.B.bles… no.
