I would like to see someone write a web browser for the Commodore 64 using the Wifi modem or something. It would be limited in colors but it would be good to see what some websites look like on the Commodore 64.
you'd almost literally have to send the C64 an image: it only has only 64k of memory (maybe that was obvious, but just in case)
The C64 has at least one web browser as part of Contiki OS.
