Experiments
This little utility allows you to input known letters from a popular 5-letter word guessing game and will show you possible words that fit the pattern. You can also input letters to be excluded. It uses a list of almost 10,000 known 5-letter words, much more than such games typically use, however it can still be helpful and/or interesting to see what other words you might have been able to (appropriately) guess.
The countdown timer can be used to display a countdown in a browser window. It allows you to choose the date and time to count down to, as well as some colour options. This can be useful for display on your own screen, or - with the correct colour choices and configuration - to display within a livestream.
