In the world of the internet, there exist numerous websites that are both entertaining and practical, adding joy and convenience to our lives. Below, I recommend two such websites for you:

1. Remote-controlled Countdown Timer: This website offers a remotely controlled countdown timer, ideal for use in remote meetings, online courses, or team projects. You can set the time and share the link with others to witness the end of the countdown together. Visit the website at: 3timer.com.
2. Remote-controlled Pixel Artboard: If you love pixel art or want to collaborate with a team to create pixel drawings, this website is the perfect choice. It allows multiple people to edit a pixel artboard simultaneously, making it ideal for creative brainstorming or team activities. Visit the website at: drawpixel.art.

Both of these websites are not only fun and entertaining but also highly practical. Why not give them a try?
