It looks good, good work. As a suggestion, I think it would better to make the transactions fill the whole screen and then get it emptied once It's full instead of hitting the surface for a sec and then disappearing.
Thanks.
That's a cool idea. I'd like to implement that actually, but the mempool can often exceed 10,000+ transactions at a time, which would be slow to draw on the screen (I want to try and keep the rain as fluid as possible).
As a compromise, you can see the mempool by clicking the screen. Transactions "enter" it and increase the count and size of it. When a block arrives, you can see the mempool decrease in size as the block passes across it.
Thanks for the idea though, it would be cool to find a way of visually representing each individual transaction as opposed to having them disappear in to the mempool.
