Until next Thursday, you will be able to see a wonderfully teletextised version of iconic C64 musician Rob Hubbard on Germany's ARD Text. For those not living in said country, you can view the artwork via that wonderful tool that is the internet.
The International Teletext Art Festival is running on ARD Text until 16 September, but I'm not sure if there's much more video game related content. There is a fantastic version of Mr T, however. Check it out, sucka!
