I had some toys like this when I was younger (I am blind.)
You can take a Rubix cube and put different textured and colored stickers on all of the different colored cubes.
You also can find a lot of information about how to modify toys for any sort of disability online. Just figure out which disability you want to adapt the toy for and do a web search.
Hopefully this goes well and if you need any ideas, you can
PM or
VM me and I'll be glad to help.
