I wanted to let you know that during this lockdown time my family has used your random card sorter to play long distance card games over Zoom. My parents (in their 80's located in Oregon) and their two daughters (Alaska and Arizona) are able to meet weekly and play a few hands of Hearts. Without your website it would not have been possible. My parents look forward to our weekly time and we will likely continue even past the virus protection time. I know there are online games that could work for the card purpose, but the ability to see each other's faces is more important than the cards. My parents are not tech savvy and would not be able to participate in anything online. So we have settled on this method of playing long distance cards.

Suggestion: If I had a wish however, I would wish that the output of the random cards were in rows of 13 (as if they were dealt to 4 people). It would make it so much easier to forward everyone's cards. :-)

Thank you!

I write and use molecular dynamics and Monte Carlo simulators which have their own pseudo-random number generators (for portability and reproducibility). These require the user to input a random number seed. If I want to perform an ensemble of N statistically independent runs (e.g., with different initial conditions), I need N independent seeds. So I use your site to generate seeds to paste into my input script, i.e., your random generator generates random seeds for input to a pseudo-random generator. Say that 5 times fast.
