How can I get my Mirror (Screen) to have some seasonal characters?

[cheminge]

So, My girlfriend likes to have drawings of special seasonal characters overlay our manual calendar.

I am looking for a fun little overlay of some events that will show on top of or beside my calendar display.

I am currently using the MMM-CalendarExt3 where I have Icons for each special event, but it is only a small icon for that event.

My questions is how can we get it like the snow flakes on top, and the snowman for winter like in the attached picture?

Maybe a Leprechaun for St. Patrick day, hearts for valentines day, Easter bunny, Spring flowers, Turkey for Thanksgiving, Santa Clause or whatever.
