Show HN: Emoji picker game for kids and dev hack for rendering large emoji lists

A few months ago, my daughter Lala wanted to "play emoji". She had previously sent one too many emoji messages to randos on my phone so I made her this game, named by her of course. It's really just a giant emoji picker but in a way it's taught her how to move the cursor, click, scroll and clear her selection so I thought I'd share it. From a dev perspective, I did learn something cool in the process too, rendering a large list of emojis is really tricky! A little hack I learnt was to force hardware acceleration with this nice little one liner: transform: 'translateZ(0)'. Anyway, I hope a few HN dad's find this useful so just putting it out there :)
