Various technologies and techniques are disclosed for providing a framework with a common set of domain-specific entity identifier types that object models representing conceptually similar entities from a domain can use to correlate to model-specific object instances. For example, a system may include a small form factor infrared imaging module to capture thermal images of a scene, which may be received by a processor to generate alignment guide information such as a user-viewable image of the scene, a user-viewable cue, and a framing reticle. In embodiments utilizing two or more such panels or construction elements, joining means are provided in the form of a flexible strip threaded through holes, an edible adhesive or flexible edible hinge. Due to the use of the scrolling unit, a simple projection system can be obtained, and color scrolling is easily performed. The cap includes a first cap engagement member, such as a detent opening, which is adapted to removably engage the base detent. The light fixture includes an attachment mechanism connected to the light fixture.
