A Little Ramble
I walked through the mountains today. The weather was damp, and the entire region was gray. But the road was soft and in places very clean. At first I had my coat on, soon, however, I pulled it off, folded it together, and laid it upon my arm. The walk on the wonderful road gave me more and ever more pleasure; first it went up and then descended again. The mountains were huge, they seemed to go around. The whole mountainous world appeared to me like an enormous theater. The road snuggled up splendidly to the mountainsides. Then I came down into a deep ravine, a river roared at my feet, a train rushed past me with magnificent white smoke. The road went through the ravine like a smooth white stream, and as I walked on, to me it was as if the narrow valley was bending and winding around itself. Gray clouds lay on the mountains as though that were their resting place. I met a young traveler with a rucksack on his back, who asked if I had seen two other young fellows. No, I said. Had I come here from very far? Yes, I said, and went farther on my way. Not a long time, and I saw and heard the other young wanderers pass by with music. A village was especially beautiful with humble dwellings set thickly under the white cliffs. I encountered a few carts, otherwise nothing, and I had seen some children on the highway. We don’t need to see anything out of the ordinary. We already see so much.

Filmspace - 2006/2007 | Dennis Neuschaefer-Rube
The works of the series Filmspace resulted from the montage of up to 300 frames extracted from films of Godard, Hitchcock or Kubrick. Pan shots as well as tracking shots and zoom techniques or combinations are used for the work. The techniques used for the production of the works are exactly those having been also used for the production of the film - cutting and montage.

Interpersonal synchronization during side by side treadmill walking is influenced by leg length differential and altered sensory feedback.

Abstract
Unintentional synchronization of stepping occurs frequently between two people walking side by side, yet little is known regarding the neurological and biomechanical mechanisms that underlie this coupling. The purpose of this study was to quantify the relationship between leg length differential, select variables related to sensory feedback, and unintentional, interpersonal synchronization during gait.
METHODS: Twenty pairs of participants stepped on side by side treadmills under six different conditions in which visual, auditory, and tactile feedback were altered.
RESULTS: When compared with an estimate of synchronization expected to occur by chance, synchronization of stepping was significantly greater in each sensory condition examined. Overall, 62% of pairs exhibited unintentional step frequency locking. Pairs that exhibited entrainment had significantly lower leg length differences between partners (independent t-test, p=.044), and a significant relationship was found between leg length difference and both difference in frequency of stepping (R(2)=.258, p<.022) and frequency locking (R(2)=0.307, p=.011). Altering sensory information appeared to have little effect on the amount of step frequency locking, but improved phase angle locking. Specifically, the addition of a mechanical coupling between participants resulted in a significant increase in the amount of time spent phase locked when compared with the case where normal vision and sound were restricted between participants.
DISCUSSION: These data suggest that unintentional gait entrainment can be reproduced in a laboratory setting using side by side treadmills, and that anthropometric properties, such as leg length, have a significant effect on gait synchronization. Further, alterations in sensory information can affect unintentional, interpersonal synchronization, but this behavior appears to be relatively robust to changes in sensory feedback pathways related to gait.
