Animation created for Gaia's data release 3 on 13 June 2022: https://www.cosmos.esa.int/web/gaia/d...

This video contains an animated infographic which explains how the wavy
pattern arises in a plot of proper motion along galactic longitude versus
galactic longitude, where the plot is made for the selection of young disk
('OBA') stars from the paper "Gaia Data Release 3: Golden Sample of Astrophysical Parameters" by the Gaia Collaboration, Creevey, O.L., et al.

The video starts out orienting the viewer with the aid of the Gaia Early Data Release 3 all-sky image of the brightness and colours of the stars. The relation with the Milky Way disk is made and then an animation follows which shows how the way the stars and the sun collectively revolve around the Milky Way centre gives rise to the pattern seen in the above described plot.
