Thanks for your comment. Since this is uploaded onto the blockchain, you will always have it as a convenient reference.

You can even click-and-drag each box and make cards of them, which you can carry around with you and flip thru them when you have time. I did that when I was studying Japanese. I found that during each day, I had much open time, when on the train or during lunch break or so, and I always had my Japanese pictogram cards in my pocket.

As for the time spent preparing all this, it's a labour of love. Truly my pleasure.

Best of luck!
