Does it only work with Elements CMS or also with the standard Elements?
If I’m not mistaken, the developer hasn’t published a post about it yet. May I suggest waiting for his post? Just to maintain the wow factor of such an interesting product. 
It’s in the store and I’m interested in buying it … @differentdan remove my post if you want.
1LD doesn’t usually post forum announcements when they release a new product based on their forum activity history, so I’m not sure if they are planning to start now?
Anyway, @1LittleDesigner if you want to remove the post reach out to us.
Also, we’d love it if you’d start posting your new store additions in the Elements Store forum. 
1LD should make more PR. I didn’t know about this product until I searched for “1LD” in the store - Perspective Motion | components | RapidWeaver Elements Store
I bought this and have the same question. Plus whether there is a sample project to look at, as I cannot get it to work for me and it is not obvious when looking at the associated templates.
I can confirm that both the trigger content and modal content are completely customizable with standard Elements. We will also be adding a demonstration project file to the package here shortly.
Indeed, the component got approved a bit quicker than anticipated, we will be making our own announcements shortly.
No need to remove this post, we will be sure to make our own announcement on the forum too 
It’s a well made component!!
