Autism Games/Activities that are good for a eight year old autistic boy.?

I'm currently working with an eight year old boy who was diagnosed with autism two years ago. Although I love working with him I'm constantly trying to come up with new activities, whether its reading neat books together, artwork, lego or cool games that are more activity orientated ones. So my question what activities or resources could i be pointed towards to further our interactions together and make them more fun:) Thank you:)
