this is a rollercoaster i made. it took me a lot of time to build. i didn't use any programs except from minecraft ofcourse. every block placed, is placed by hand. the rollercoaster got an awesome little parkour, alot of random stuff. and a nice firework show at he end :D takes about 30-45 minutes. so take your time, and i hope you will enjoy it.
