For me it's missing something to illustrate the relationship between shutter speed and motion blur. If the subject was a running fan instead of of lightbulb that would have been ideal.
If I ever find a good moving prop like a small fan, maybe I'll also re-shoot new previews to demonstrate how shutter speed affects moving objects.
Now, I'm just not sure how would one simulate a running fan with a picture. While for a static image you can have separated foreground and background and then apply effects for simulation (I know iPhone HEIC images have this property), for moving images you have to simulate the blur and the stillness, which is probably more difficult in terms of coding.
Why simulate? Most modern cameras can be controlled through USB. Just actually take each one (except for ISO, which you can easily fake), encode the frames in a reasonable bitrate MP4, then have a lookup for the frame in the video. :D

I don't think it's necessary for this app. This is simulating what the camera sees, not what our eyes can see.
