There are various free resources on synesthesia
Many of the researchers in synesthesia have resources too.
The best place to start is to join the Synesthesia List run by Sean Day un the USA. The list has researchers, artists, parents, synesthetes and others, raising issues, discussing syneshtesia types. The list is moderated by Sean.
Of course youtube has several videos now and Amazon sells quite a few books too.
Please come back later as I am rebuilding this page.
