1. Desire for better/completed animations
Many commenters noted that the site is useful but incomplete or sometimes inaccurate, and they wish the remaining movements were animated or corrected.
- WillAdams: “Really wish that the folks doing the 507 Mechanical Movements would finish the balance of the animations.”
- frnz: “The first two examples I looked at … have the ropes partially going in the wrong direction.”
2. Value as training/educational data (for humans and AI)
The collection is seen as a rich resource for learning mechanics, brain‑training, and as a dataset for AI‑generated animations or simulations.
- Animats: “That's a good training set for animation AIs. Image generators are terrible at mechanical understanding at the moment.”
- MisterTea: “For me it's a great dataset to train my own brain. This way when I'm in the field … No accounts, internet connection, or compute needed!”
3. Appreciation of the site’s simple, old‑school web feel
Users repeatedly praised the low‑overhead, nostalgic design that focuses on content without bloat.
- mklyachman: “Honestly, I miss old‑style internet sites like this. Nothing fancy, just good niched out information. No 300 MB loads for something that should be simple.”
- WillAdams: “One of my favourite sites! and an interesting example of that class of sites which are book made into sites with animations/interaction …”
