Mark Rober shows an automatic bullseye dartboard that tracks a thrown dart with motion capture and moves in real time so it always hits the center. He spent over three years on the project.
Why Hacker News points people here: HN calls it a great, impressive engineering project involving real-time trajectory calculation.

“Another great video is his automatic bulls eye dartboard [2].”
Mark Rober's automatic bullseye dartboard.
The actual video is by Mark Rober and man you gotta check out his YouTube channel [1]. I've been in a technical slump here recently and watching his videos totally re-energized me. He reminded me how great it feels to explore, build, and solve problems. Another great video is his automatic bulls eye dartboard [2]. [1] link [2] this video
“even more impressive than this glitter machine IMHO”
Dartboard project calculating projectile trajectory in realtime.
This is an an awesome project... the kinda stuff I wish I had more time to hack away at... In the video he mentions his automatic bullseye dartboard project... even more impressive than this glitter machine IMHO: this video Calculating a projectile's trajectory in realtime.... wouldn't even know where to start. EDIT: dartboard code from that youtube link: link
“a dart board that does the same this as this backboard, but with active compensation”
Dartboard with active compensation, related to the backboard.
Mark Rober (who is linked elsewhere in this thread for a dart board that does the same this as this backboard, but with active compensation) also did a video on how carnival games are rigged.
