Each of the above maps represents objects mapped on OpenStreetMap which have a tag which corresponds to a single word. Together they spell out a topical phrase:
Happy. Actually name=Happy's as for some reason I had not spotted lots of name=Happy in Europe.
10th. A minor fudge, using tiger:name_base=10th and restricting it to Pennsylvania to reduce the amount of data returned.
Birthday. A couple of retail places in Japan have name=Birthday.
OSM, A real fudge, I used source:name=OSM (an interesting recursive defintition in itself)
SK53 received a Garmin GPS as a Christmas present in 2008. Foolishly he downloaded OSM, noticed a nearby street was missing, and promptly sold his soul to mapping. Since then he has mapped large parts of Nottingham, verified about half of Maidenhead, takes a PC on holidays for mapping, and now has 2 more GPS gadgets, but still feels the need for more.
