I finally found a place about 4 suburbs away from home that will do a weekend deal for the projector and screen for $150 from Friday to Monday. The worst thing in web searching these days are those "fake search engine" sites that intercept your request, reformat it unreadably and recommend stupid results which are probably just paid advertising. I think there was some furore a few months ago when Google said they'd block these irritating sites in their search results. I hope they do. It's not Friday, but here is a quiz question I'm going to ask people on Saturday night. Using only mental calculations and guestimates ... If our sun was the size of grain of coarse beach sand (about 0.7mm across), at that scale how far would it be to our close neighbour star Alpha Centauri where the Space Family Robinson blasted off for back in 1997?
