Guides for films telling you when it's ok to dash to the loo at the cinema without missing something big or exciting or important.

Inventions I had that have been overtaken or made redundant... Repurposing / reusing cash machines to print walking or driving directions. Phones wiped that one out!

Inventions I had that have been overtaken or made redundant... Cooking tapes. The instructions are timed for when you need to do them.

Digital radio but *twist* it's not wildly expensive.

Optional subtitles for TV that explain who people are and what's going on, for viewers with limited attention.

Footballs that find their way home if you kick them over the fence.

Interfaces for white goods that you can understand without poring through the manual. A toaster that can tell how browned your breaded goods are and stop before they burn. Bicycle tyres that tell you if they have a slow puncture. Vegan cheese that's just a little bit chewy and crispy for pizza.

Great @scalzi.com novel about this.
