I didn't really sense a concept for this flash, it mainly seems like lines connecting to form random objects. It was still an entertaining flash though. I thought the background looked neat and you used color well. I enjoyed the part where the two tubes were both filled with color, it had a cool effect on the flash. The music was a nice addition too, it went well with the animation.
The concept and somewhat repetitiveness was all that I counted off for in this flash. Aside from that, I thought the experimental feeling this flash envoked made it look different and creative. Smooth animation and good music was what made this flash interesting. Overall, it was a submission that appeals to your senses. Keep up the good work!
