I've designed 3 different versions for this Hackathon.
Milestone Reached - animated text stomp version that emphasizes the milestone with thoughts on scroll-stopping impact that then follows something subtle for the viewer to easily digest the text content over top of the video (which in itself should be a primary focus)
Money Emoji - Pretty self explanatory. Similar to the inspiration provided this scrolling animated emoji is scroll-stopping and eye catching
Iridescent Shapes - This one is relatively subtle but matches the look and feel of the Contra platform.
Original as-is videos to follow in the comments below as well.
