Just a thought. Maybe no one will use this but it is an interesting idea.
Using Cloudinary and any Transformation that uses numbers…
The direct link to the image pixelated by a power of 85
Notice the 85 there in the middle.
We can change that pixelation number every time someone interacts with the app (fills out a form/completes a challenge/assignment)
Here is the app
The form in the app will reduce that amount by 5 each time until the number is zero (no pixelation)
So maybe an image becomes more and more clear as people (students) interact with the app.
Other examples, the image could ‘grow’ with each interaction. You could make it more or less blurry!
Again, maybe not much here, but it sure if fun to manipulate the images through URL
