we got one of those back from our visit to the UK weather shop
works really well, the kids though it was reall cool
it projects the current time on the ceiling as a red numbers, so at night if you want to know what time it is (i.e a kid is yelling in the middle of the night), you can easily see it , its up there on the ceiling…no need to raise your head and try and peer over and find the clock dial, which is often behind something, etc
idea:
OS should be able to also display the current weather data from say a OS WMR968 station as well!
