It represents the components of wild, marine, and mountain life, where the visitor can identify closely the old traditional customs of the country and the special characteristics of old houses, handicrafts, patterns, and forms of living.

Central Bangkok and the Chao Phraya River are seen from an abandoned skyscraper in Bangkok April 19, 2015. The abandoned building, known as Satorn Unique, dubbed the “ghost tower” was destined to become one of Bangkok's most luxurious residential addresses but construction was never completed as the Thai economy was hit during the 1997 Asian Financial Crisis. Now, many travellers visit and explore 49-storey skyscraper. (Photo by Athit Perawongmetha/Reuters)

Throughout time, people invented and reinvented rollerblades. Of course everyone’s dream was to combine them with regular footwear, so that at one moment you’re riding down the road, and in 5 seconds you’re walking into a shopping mall, without the mall cop chasing after you. The most resent inventions were heelys (sneakers with a wheel located in the heels) and Xsjados (aggressive skates, the exterior of which could be removed to reveal regular sneakers). In the past, people made similar attempts, however, these inventions were very inefficient and the trend never caught on. Omnia’C has found and made photos of one of such inventions: pop out roller skate sandals all the way from 1970s. Though their design is pretty cool, it seems like they would be very uncomfortable, since they totally lack ankle support.
