How do you determine the “best” pelican? I couldn’t see much of a difference between extra high and max.

Even if it is training on the Pelican bike test by now it's impressive and most importantly helps (at least I hope) svg animations and creations as those are pia to do.

> The wheels in the video are rotating in the wrong direction I thought they were going in the correct direction until you mentioned that. Perhaps you / it created an unintended bistable illusion :)

Are the wheels rotating in the wrong direction? I stared at it they seemed to reverse. Perhaps a bit of a optical illusion. Looking at the SVG, the direction is missing but the default is clockwise. So I'd say it's good!

That's pretty nice. Here's Gemini 3.7 for reference: https://simonwillison.net/2026/Aug/13/llm-gemini/ I found Gemini's one much more impressive initially, but on closer inspection it's got a whole bunch of issues. Missing leg, objects overlapping etc. (We might say the seat looks "uncomfortable" xD)
