A Memoir Blue

When you tune the radio, pixelated images will come into focus. When you press the two buttons on top of the radio, there will be two animations for each image -- the achievement description should probably say "View all of the animated images available on the radio." (It didn't pop for me when I just looked at the still images.)

The radio sequence is shortly after the beginning and unmissable. To see all images for the achievement you have to move the red "needle" to all "high" white lines and push the two small buttons on top (Button 2 and 3 from left, don't push the first button on the top of the radio)


In case you want a video for this achievement and all other achievements I have a 100% walkthrough incl timeline

When you get to the radio scene interact with the rotating button and rotate it to the big spike.
Press 2 buttons ( top left on the radio ) – leave the big far left one.
Do this for the first 6 spikes to see all animations. When you get to the 7th spike the achievement will pop.
