Hello StreetShowKeith, All of the effects on the trailer, with the exception of the color change are classic rubber band effect. These can be learned in any of the classic rubberband magic teaching dvd's like Dan Harlans Magic with Rubber bands 3 dvd set band shark, or Extreme Rubber Band magic.
Just do a search on rubber band magic and you'll find amazing effects by Casshan Wallace, Russell Leeds, Hanson Chien, Marcus Eddie, Daniel Garcia, Dan Hauss, Blake Vogt and so many others. Rubber band magic is a sub genre of close-up magic and more and more effects are being created and evolving many from the people I have previously mentioned.
The band are meant as a performance grade tool like a deck of cards or a thumb tip. If you do any rubber band magic then these are the bands you'll want to use.
with that said I have created many entirely new rubber band effects that have never been seen before. These effects will be released slowly over a period of time. The reason is it does take time to film and edit the downloads.
