I want to mount my Nexus to a wall for about 3 hours. For those who are not familiar with scientific posters: During a conference a large poster is attached to a removable poster wall, usually with doubel-sided adhesive tape. I want to place next to the poster a Nexus 7 that permanantely shows a video clip, related to the content. The nature of the wall is unknownh, but usally they have a table top like surface, usually smooth, sometimes with soft material to allow needles to be inserted. My question: How can I mount the Nexus on this wall in eye height? I could add adhexive tape to the backside, but I am not sure whether this will hold it for three hours, especially because its own heat may losen it. Another possibility would be to put it in some sort of transparent plastic that is fixed by ropes to the top of the poster wall. But this may look quite ugly. Are there other solutions except holders that require drilling of holes (no solution here).
