Ok maybe a timer can never be super "fun", but this timer gets close. It's called the TickTime Timer, and I use it whenever I want to say, sketch for 30 minutes straight with no interruptions. I *could* use my phone for that, but I like this little device more.
I did a quick review of it below. It's perfect if you want to set a timer for work, cooking, or pretty-much anything.
If you are interested in picking up one for yourself, you can find it on Amazon here!
