Their like Ice Cream Vans, But sell sweets instead.
Whats good about this is Sweet Vans drivers can work all year round unlike Ice Cream Van drivers. The downsides to this is only people over the age of 18 will be able to purchase the sweets, because you should never accept sweets from strangers!
Its like google street view, but instead of pictures of streets, viewers will be able to make a virtual ramble though peoples gardens.
I think people with nice gardens will love this, as they spend all that time gardening and it stay hidden behind there house.
Of course the downside is you will have a google camera crew climbing over your fence and taking pictures of everything!
My other idea, which is similar, is 'Google Trespasser View' like Google Garden and Street view, but they come in to your home and take pictures of everything. Thus you will be able to make a virtual tour of everyone's house.
