On the contrary, video synthesis has a long &
interesting history. The most successful analog
design was Dan Sandin's IP, a modular real-time
analog image processor. It was never available
commercially, because Dan gave away copies of the
plans (I have a set in my library somewhere) and
arranged that it was easy for DIYers to get PC boards
and parts kits, but more IPs got built than any commercial design.

There's lots of information on video synthesizers here:

including discussion of Dan's IP:

If I were undertaking such a thing today, I'd go digital.
Contemporary video input and output is all digital, and modern
FPGAs are cheap and fast enough to do very interesting things.
