Graphics on " Dark Side of the Moon" cover

[Benni]

Hello,

this is not entirely music related but I´ll try here :

On the album cover, the ray of light is split in the prism and the rainbow colors emerge.

Then the green line shows a heartbeat pulse.

I just can´t find the correct wording for this "pulse graphic", anyone here in the know ?

Furthermore, where can I find such a graphic line for a single-cylinder 4-stroke engine ?

Sinus rhythm.

You want an "ECG" of an engine?

What do you want it to show?

[Benni]

Blaney, thank you, mind was blocked and luckily I don´t visit doctors on a regular basis.

Yes, I want that, for a modern varitation of a very classic bike paint job.

Electro Cardio Graph is the correct name ?

[Blayney]

Yeah. Often confused with an echocardiogram.

I think the ecg works by detecting electrical pulses caused by heart muscles contracting. I'm not sure how that can be replicated for an engine?

Oscilloscope diagnostic traces of ignition pulses might do the trick : https://www.google.co.uk/search?q=ignition+oscillo...

Marshalla : That is a very good idea, like it, and graphically doable for me as n00b.
