Toad Visual Neurons

Weekends are for internet rabbit holes: watching Jurassic Park (for the millionth time) and discovering some really interesting research on how toads see. Above are stills from a video by researcher Jörg-Peter Ewert, testing how toad neurons react to various worm-like stimuli. (Warning, the video includes some images of lab animals.)

The pattern testing, and subsequent neural network, seem very relevant to computer vision work today (bonus for day-glo yellow too).

Growing Shell Forms: Progress

More progress “growing” heatsink shells – each of these is built up using successive images in Processing, then converted using Fiji (similar to how an MRI can be turned into a 3D model). They’re then cleaned up and rendered in Rhino.

The fingers will act as heatsink fins, drawing up heat. Spirals, concentric circles, and various parameters for random growth change the form.

Experimenting with sharp fins at the top.
