Awesome symptom no. 12
Unusual visual-spatial skills

Some autistic people may enjoy modelling, or imaginatively laying out gardens and interiors, or making intricate paintings/cartoons/embroideries, or drawing out maps, or even (for some) making and fixing things.

For example, I'm rather good at putting together IKEA furniture (even if, ahem, I might not manage to go to IKEA to buy it)!
