+snaking paths, pattern growing on the screen
+with a pre-defined sum over rectangular region
+
+so let's pick 3 region
+
+to demonstrate 4 of those pltos at the same time
+
+4th one is the total
+
+bottlenecked on the stage speed - in step scanning
+in fly scanning
+
+from streamdatum, from stomp serialization
+
+from run engine serialization of the scan spec
+
+JSON - serialized version of the scan spec
+to turn back
+
+summary at the bottom?
+
+button to run again?
+
+also show the raw image
+
+then a faster camera - stages already can fly scanning
+
+probably 5 frames every half a second = 10Hz
+
+the snake frames are 100 by 100 maps likely
+
+10Hz will be the fastest we can see enough light
+
+but thne 10 minute scan?
+
+2 minutes as expected duration
+
+after clicking a button
+
+we see a pixel with intensity
+
+we histogram them in terms of maximum intensity
+
+the initial pixels need to get dimmer
+
+we update live the reference value
+
+davidia - davidia shoudl already do the histogramming
+
+the sum - numpy array?
