Ask HN: Alternatives to Scratch for a blind child?

My friend’s children are starting their adventure with programming at school with Scratch. Unfortunately, the eldest one is blind, and as Scratch is visual, he won’t be able to use it. A pity: the kid has probably the most vivid imagination of all people I know.

Can you recommend an alternative? Something tactile or audial, perhaps? A quick googling yielded https://codejumper.com/ – is it worth the $1K it costs?

Personal experience reports are most welcome. Thanks!

Usually Apple has been pretty good with accessible features. I wonder if they built it into to Playgrounds too.

Can something be done with an overhead camera, and a bunch of cardboard cutouts using QR codes? I remember one of the (big name?) universities had a project along these lines. In their case they used different patterns of coloured dots on objects, and every object in the room was mapped to a virtual equivalent. Interaction with the computer was solely by moving objects around in the room. I can't find it on Google. It might have had a connection to the Dynabook project? They probably have code ready to go.

Maybe you could have different shaped bits of paper which implement blocks using javascript? Add a "print" function and the programmer could consolidate something they have written using multiple blocks/sheets into a single block/sheet, so allowing more complexity in a smaller space? Alternatively, can it be mapped directly to scratch instead of javascript?
