Channeling one's inner hippy, a peace sign can be card. This had to have already been done a million times, peace sign as card.
A peace sign is a crimp.
A crimp like this can move a whole page of content attached to one of of its triangles.
[It also displaces the central fold by turning an "|" valley-type score line into a "Y" with two valley-type score lines and one peak-type score line. Paper mechanism intended for the central fold valley score (most) and on recto vs left-o action (most) is moved to either side or both side, but that advantage is not availed here.]
The empty space can be filled in with a new square with its own score line, to tuck back in origami-style.
Pow! Flower power. There is not much to it except the card gets bigger when opened and that is a bit startling, nothing pops up. The inserts added to the crimps slide across both pages as two scoops. The flower painted twice, once on the background and again on the blades. The large blades cover the first flower, they are seen as the blades with petals painted on them slide over the background appearing to double the number of petals as they slide, then obscure, as old camera shutters used to close with blades that slide across each other to form a specific aperture.
