I was inspired by the blog post, http://blogs.sas.com/content/iml/2015/12/16/polar-rose.html  to make a beautiful Valentine with SAS.  I was thinking as well you could also make a data set with people's names and use by group processing to make personalized Valentine's but for now you can see below the basic idea.  I had fun make these.  The roses are random, so each time you run the macro you get slight differences in the selection of roses.

This post *totally* makes my day, @LauraRK! Love what @Rick_SAS did for Valentine's Day 2015: https://communities.sas.com/t5/SAS-Analytics-U/Give-A-Geeky-Valentine/m-p/164135/highlight/true#M806

Couldn't attend SAS Innovate in person? We gotchu. Access on-demand content now!

Happy Valentines Day, just bumping this up, as it is that time of year again.
