This software allows HVAC installers, primarily retrofitters, to build the very best ductwork transitions they possibly can while in the field. Doing ductwork transitions by hand can be a tedious and labor intensive process, but is very often necessary in order to achieve good airflow. When you cut each piece you have to keep track of which side will have tabs, how long the tabs are, and sometimes even if you do it right you end up with gaps or noticeably crooked faces. If you've ever found yourself building a transition in the attic of a three story house then you will absolutely love Field Fab. Now you can take your measurements, input them into Field Fab, and you can then view the results via Augmented Reality using your iPhone or iPad's camera before even cutting a single piece of sheet metal! This saves you trips back and forth to the van and saves you the hassle of bringing a large piece of sheet metal into the attic. Sometimes it's nice to have the transition ordered at your nearest sheet metal fabricator to have delivered before install day. Well with Field Fab, your sales crew can take the measurements and view them before an installer even shows up. Field Fab includes a sharing feature that allows other people to view the transition you made in FieldFab by sharing a link, which means it works over text message and email. No attachments! If you would like attachments, FieldFab also has the option to export to PDF. FieldFab is open source and available on GitHub for anybody to download. https://github.com/robertmsale/FieldFab

Turn your iPhone or iPad into a touch-first projection mapping and video mapping studio. Lazy Lighting lets you warp videos, photos, live camera feeds, animated drawings, and generative VJ visuals onto walls, stages, sculptures, windows, objects, and multi-surface installations—without a laptop. MAP ANY SURFACE Create squares, circles, custom text, cubes, boxes, image silhouettes, and hand-drawn outlines. Drag corners directly on screen to align each projection, bend edges around curved forms, then use masks and cutouts to control exactly where every visual appears. Map several surfaces at once. Assign different content to individual shapes, layer visuals with independent opacity and ordering, and save projects to continue later. CREATE LIVE VISUALS • Explore built-in visualizers, VJ loops, generative shaders, gradients, tunnels, neon effects, and shape-aware animations • Import videos and photos from your device • Use a live camera feed as projection content • Draw and animate original visuals by hand • Crop, fit, mask, layer, and apply real-time effects including kaleidoscope, tile, slide, rotate, zoom, blur, monochrome, invert, and color cycle • Make visuals react to audio or control parameters with MIDI • Animate controls with BPM-synced LFO and envelope modulation • Use hand and face tracking for expressive control BUILD A COMPLETE SHOW Create scenes and switch between them live, or arrange them on a timeline. Add an audio track, trim and duplicate clips, automate visual parameters, and move between looks with fade or dissolve transitions. Export the finished projection-mapped show in 720p, 1080p, or 4K with audio. Save it to Photos or send it to a compatible receiver running Lazy Lighting Link. EXPORT ONCE. PLAY WITHOUT YOUR PHONE. Once the transfer is complete, Lazy Lighting Link saves and loops the show on the receiver. Close the app and free your iPhone or iPad—the projection keeps playing without your device remaining connected. CONNECT YOUR WAY Connect by HDMI with a compatible USB-C or Lightning adapter, use AirPlay, or connect through Lazy Lighting Link. External display output keeps the controls on your device while the visual output fills the projector. Lazy Lighting is made for projection artists, VJs, DJs, musicians, performers, stage and event designers, galleries, installations, window displays, parties, home ambience, and Halloween, Christmas, or holiday projections. Create the map. Build the visuals. Perform live—or export once and let Lazy Lighting Link keep it playing. A compatible projector or display and a wired or wireless connection are required for external output. Lazy Lighting Link export requires a compatible receiver on the same network. Some features require a subscription. Terms of Use: https://lazylighting.com/ios-terms Privacy Policy: https://lazylighting.com/ios-privacy
